Can't pull through clicker at 18m, but fine at 10m?

Hi all,

Not sure if anyone has gone through this before, but I find it really natural to pull through my clicker at 10m, but as soon as I move my target back to 18m, everything just seems to fall apart. All of a sudden I feel like I have to expand like crazy (so probably falling short somewhere else), and I can barely get through the clicker or sometimes I'm expanding for literally 8-10 seconds.

Is this target panic or maybe something similar? Having a target at 10m seems to be fine and it's also difficult to pull through the clicker at an empty bale at 18m

Note:
I thought it may have been fatigue, but I would go back to 10m after shooting and pulled through just fine
