1. download attached AS_A1.fbx (15frames) and AS_A2.fbx (28frames)
2. Rename attached AS_A1.fbx to AS_A.fbx
3. Import the AS_A.fbx with SK_Mannequin skeleton
4. Open the animsequence
5. Create a curve in curve editor pane
6. Add some keys to the curve
7. Save the asset
8. Rename AS_A.fbx to AS_A1.fbx
9. Rename AS_A2.fbx to AS_A.fbx
10. Reimport the animsequence and see curves

Result:

The curves are not scaled. This behavior is not compatible to UE5.4 or earlier
