In Clique I see... disable out of combat clicks, when party members are in combat.
But nothing for the reverse, to stop clicks from doing whatever in combat.

Could drag the Repeater Region elsewhere on the screen.
Have CTM on, for the healer.
And see if that is working (moves your toon), while in combat.

Could also try updating your addons, although I've not done an update in a while, so not sure that would do anything.
Or possibly get rid of the saved variables file, and set up Grid from scratch.
