Return of Reckoning

Hey,my m4 somehow bind on action bar first slot,i cant remove her when i try remove have this message like on screenshot.
Its only bug in assault stance.If i remove m4 from morale bar it remove from action bar too but play without m4
Any suggetion?

This seems to be a bug of the Addon TexturedButtons, no clue how to fix tho.

Edit: It's Morale Circles, not TexturedButtons.

Oh,thanks.
I disable texturedbuttons,remove m4 from action bar,turn on addon and all good.
