Using Macaroon with Dominos

[alcaras]

I'm trying to use Macaroon with dominos, to supplement my existing bars with a few new ones.

Unfortunately I get a weird effect -- that some of the buttons on Macaroon seem to share with buttons on the dominios bar. e.g. I drag a button onto dominos, and it shows up on Macaroon, or vice versa. Worse, this happens on every character except the character I set up Macaroon on, where inexplicably, it doesn't happen.

I've checked Macaroon settings and I have no idea what's causing this, nor can I somehow desync these two bars. I've searched and haven't been able to find anything about this question either, thus leading me to post this.
