Can't deploy

They start blank. Press a button like your going to change things.on play station it’s square. Click  on specialist even though it’s blank it should let you select something. Then that enables you to play. Still it won’t let you pick your own weapons so you’ll have to creat your own load out in the options menu. If this still don’t work I’m not sure. It’s very frustrating I know. Hopefully Dec update fixes everything
