Troubleshooting Help: On entering combat, some Draugr chase me, but do not attack

TL;DR: I've been working hard to build a fun, heavily modded game, and things were great until I noticed that some draugr in Bleak Falls would attack me, while others wouldn't. This is game-breaking for me, and after hours of testing, and Googling, I've turned to you guys for help. I'm pretty desperate to fix this, and any help will be greatly appreciated.

Description: I've been doing a heavily modded playthrough based on the latest S.T.E.P., with several other hand-picked mods installed. After several hours of fun role-playing (over days), I got to Bleak Falls Barrow. I cleared other dungeons before without any trouble. Everything went fine with Bandits, Draugr etc. attacking me and giving me trouble. At one point, I ran into a Draugr Wight who would not attack me. He would draw his Axe and chase me around, or run away sometimes, but he would not attack. I could kill him easily enough. The troll in the next room attacked me just fine, though the room after that had a draugr who exhibited the same problem. Once I got into Bleak Falls Temple, I met a group of Draugr, out of which only one exhibited this behavior.

Observations:

1. The Draugr did not T-Pose

2. tai/tai on the console - Draugr didn't attack, but commands worked

3. tcai/tcai on the console - Draugr didn't attack, but commands worked

4. I tried reloading but faced the same problem consistently. I could reproduce it in the same rooms

5. I tried disabling Ultimate Combat from the MCM but faced the same issue afterward. I also disabled NFF from MO2 on top of this and checked, but that didn't help. I doubt NFF has anything to do with this in the first place.

6. Enabling/Disabling the draugr after getting its Ref ID using "More Informative Console" got him to work normally. However, I can't use this workaround for every single enemy with the bug.

7. Although several people on Google faced a similar issue due to being in the Draugr Faction/Wolf Faction/Vampire Faction etc., they experienced all of the enemies becoming friendly. In my case, I do enter combat, music plays etc. Further, not all draugr exhibit the bug.

8. I've also read the Beginners Guide, Troubleshooting Guide, as well as some results from Google, the Mod Pages, Forums, without any luck.

Combat Mods: Ultimate Combat, CGO, AGO, TK Dodge, TK Hit Stop, Ordinator

Timeline:

1. I have been playing a character with Alternative Start, and I faced no issues for several hours, even when I installed new mods and tested.

2. Yesterday, I tested some new mods on a new save, then disabled them

3. I loaded up my new save today, and things went well for some time. After a while, I faced problems.

EDIT 1: I have sorted with LOOT, but if you find any issues with my load order, do let me know.

EDIT 2: Based on my research, I found some people were able to solve similar issues (Out of multiple enemies, some would not attack) when they noticed that they noticed that a high uGrids value caused them to hit the max NPC AI limit. My uGridsToLoad value is 5, and I don't have any population mods. The problem happens even with a single draugr. Since this does not match my case, I've started exploring the Spells/Effects on the Draugr using SSEEdit. I'd be grateful for any help.

EDIT 3: I've noticed that enable/disable on the draugr changes the draugr. For example, the pre-reset draugr has a 2H Ancient Nord Battleaxe, but this new one has a 2H Anicent Nord Sword.

Edit4: I turned of all the combat mods and still observed the issue on an old save. On the other hand, I couldn't reproduce this on a new save with a Lvl 1 character. It may be that this bug only occurs several hours in...
