Bug with "Rigging in Unreal Engine Workshop" in 5.7?

@Epic_ELT - I’m following along in the Rigging in Unreal Engine 5.6 Workshop using UE5.7. when i get to ~1:53 in the Day 2 video with Ferris Webby, i get different results than what is shown in the vid. the L arm and R leg “twist” are seemingly random offset. I started from scratch a second time and got the same results & scoured the graphs to see if i did something wrong. I even started over again in UE5.6 and there i don’t get the issue. I’ve compared the graphs in both versions and as far as i can tell they are identical. the complete version of the rig (supplied in the project files) works fine in 5.7 so i’m at a loss.

anyone have any idea what i may be missing or is there an issue/bug with translating a 5.6 tutorial to 5.7?
