DDJ XP2 Workflow Issue Report

When a controller is plugged into Rekordbox Dj, sampler is on screen no matter what pad mode the controller is in. When plugging in the XP2 to Rekordbox Dj, it only shows on screen whenever pad mode 4 is selected. Any other pad mode it removes from screen. If both decks are on pad mode 1 for instance, you can click the sampler module back on but the moment you switch pad modes again it turns off .. Please advise
