When pressing play, all custom toolbars replicate and grey out

Hopefully this image can demonstrate my frustration.
When I hit play, all the non-standard plugin buttons were cloned and placed in the toolbars. I’ve removed most of them, but it is rather curious.
EDIT: apparently, the colorful ones are the “fake” buttons and the greyed out ones are the normal ones, because when I hit the rewind button, the greyed out ones turned colorful and stayed.
