Question about vassal's succession law

Discussion

Heyo, i want to ask about vassal succession law in Japan

at my first playthrough, when i got shogunate and had primogeniture law (both that i got from innovation and realm law), everyone is automatically have the same primogeniture law

couple days away, i did my second playthrough and i did almost everything the same but then i noticed that all of my vassal have equal partition law, and somehow i cant change it unless i (using console) took the title, add succession law manually for the title, give it back to my vassal. If i give the title right away it will be automatically equal partition with a note that "the tribal ruler cant change"

the only different thing is i used RICE and EPE mods this time

what i have tried so far

  1. have the highest authority, change my succesion to ultimogeniture or other law succession, but all vassal's succession stay the same

  2. using console command effect every_vassal_or_below = { set_succession_law = succ_primogeniture }

  3. tried new gameplay with speed conquest using console, have a high authority, change my succession law, but still my vassal's succession stuck at equal partition

Here is the screenshot
