Distortion World won't reset boulders after leaving?

[Butterdove]

I am unable to pass through zone B6F of the Distortion World because i accidentally pushed a stone down the wrong hole. I tried exiting the Distortion World to reset it but that did not work. I am not sure if this is a bug or not. Thank you for your help.

Is the boulder completely gone from where it originally was? The Pokemon will not be, but the boulder should have gone back to where it was originally.

This person seems to have had the same issue as you did and managed to get it resolved here, hope it helps you too.
