Action bar 4+

Does this bar not reset when changing classes for anyone else? Its really annoying since I dont just throw all my buttons in a row they are set up in a manner that makes them easier to find/think of, so I need 4 bars as opposed to 3... but when I swap to pug, bar 4 still has my warrior abilities

I don't remember where exactly it is, but you need to turn off sharing. I believe bar sharing between classes is automatically on for bars 4+.
