Take 2: Why does resolve freak out sometimes when smoothing spline points in Fusion?

Help

#Issue: Most times, when I select one (or multiple) points to smooth ('s' key, or curve icon in the spline panel), Fusion makes a perfect curve.

Other times, it completely freaks out.

👉 Here's a video to illustrate what's going on:

As you can see, the smooth s-curve only occurs SOMETIMES, and only if I select two specific points. Everything out of that fails/goes crazy.
If I try this same selection logic on a different Fusion comp, I get different (worse) results...
And no, I don't actually want to modify the top two points, just showing for illustrative purposes. My aim is to ease in and ease out, which SOMETIMES works

So, how do we un-spaz this logic and get Resolve to behave?

Or is everyone just living with broken software?

Never had this issue until recently...

Specs: Resolve v20.3.2 b9 | Studio | Win 11

As always, no need to reply with 'read the manual'. Imagine I already did. Now I'm here, asking Reddit. Deal.

I'll mark both (original/this post) as solved when either of them are.
