How to bypass the king bug in the anti|chess study?

How can I move the king in the anti|chess study? Didn't figured it out yet -even the setting is already on Anti. Mostly I have to ask my those who joined to move the king for me.

Kind regards,

** because the king is check and so still bound on chess rules.

The host should be able to move it. Though it does seem like some can move it and not others, I have no idea why

The problem still exist in each study I made. I played with all settings possible.. non of them worked for the King.
