GASP Aim offset Head snaps back

Hi everyone,

I’ve been dealing with a persistent issue in the GASP (Game Animation Sample) project using UE5.4, specifically related to Aim Offset behavior.
When my character is looking around using the Aim Offset system, the head turns left and right as expected. However, **when the aim angle exceeds the defined range or returns back to the neutral range, instead of smoothly blending back to the default position,
the character’s head suddenly snaps back with no transition.

This looks very unnatural — I expected a soft, natural return to the default (0,0) pose, but instead I get an instant “snap.”

I don’t think the issue is caused by the Animation Blueprint or Character Blueprint. I’m sure I haven’t made any recent changes. (Replaced abp and cbp from original gasp and nothing changed.)
Thanks a lot in advance!
I can share screenshots or video if needed.
