Help FOP (FreePBX

I would like to change the layout of my panel so that I can see all 23 channels of my PRI. I have done this before in the past but now I can’t figure out where the op_buttons.cfg is being configured from.

It does not appear to be the following as I have renamed the files to “.bak” and the op_buttons.cfg is still being configured??? Is there now another file that does this work?
