When Cooking and looking at the 'Knowledge Description' for any recipe by pressing X and then pressing B to cancel, the entire process of Cooking is cancelled, but the 'Knowledge Description' window remains in the way. Pressing B still does not cancel out the 'Knowledge Description' window and you are stuck from character movement or taking any actions. All Menu settings work and 'Disconnecting' and rejoining the server, or a different server, brings everything back to normal. This action can repeated multiple times with the same result.

Yes this also happens with alchemy. Please fix guys.

The work around that i have found is- Press the view/select button (the one that expands chat) it will remove the other popup box.

Have the same issue with the cooking knowledge description,  work around for me is to bring menu up (select button) then change server.
