Aimoffset with base pose causes arms glitch

Hello,

So I have an Aimoffset asset and an Animation Sequence. The Animation Sequence is the same animation used as the center of the Aimoffset.
Within the Animation Blueprint, I’ve setup the Animation to play and it works fine, as seen in bellow screenshot:

If I instead, use the Aimoffset without a Base Pose, it works correctly too, as seen in below screenshot:

But, once I connect the Animation Sequence to the Aimoffset, this is what happens with the arms:

And here is how it looks with Aimoffset slightly changed:

Any help is appreciated.
Thanks.

EDIT: Just updated to 4.5 and problem still persists.

Solved by setting the Base Pose Type to selected animation frame.
Thank you.

Where in the original skeleton?

In each animation asset.

Thanks, got it.
