Pose Asset and Animation Curve Evaluation Mismatch

Hello, I am looking into how to properly debug this issue I am having with multiple poses in a single pose asset. Basically:

I have about ~100 poses in my pose asset for facial animation. When they are hooked up to a facial ROM, they evaluate as expected. However, when I try to swap to a short animation sequence, the pose asset is driving the animation curves just fine, but it doesn’t appear correct. The pose asset is setting the animation curve values differently than expected. I tried the “additive” option in the pose asset, but the pose asset still drives the curve values incorrectly.

Does anyone here know what might be causing this issue? Do I just have too many shapes in my pose asset that is making the animation curves evaluate incorrectly?
