Issues with aim offset

Hello, I made an aim offset that seems to work correctly, however when I try to blend it with other animations in an animation blueprint, it has a strange behavior.
Here’s a few pictures:

My Aim offset file, looking up, works fine

Animation blueprint, simple idle animation

and finally, I connect the aim offset

I tried to connect the aim offset alone, and it works:

Any ideas what might be wrong?

you should make a cached pose for blending. also why put your aim offset in the idle? thats the problem. your idle should be alone in one state and your aim offset stuff should be in your main graph to blend so get rid off the aim offset and put it here:
