Reply to Kontrol F1 - Issue with Dual Mappings

I am running the native Kontrol F1 mappings (for remix decks) in addition to Tekken's F1 Ultimate F1 mapping. I find that swapping between midi/native mode is unreliable with shift browse. Sometimes it works, and sometimes I can only swap between the Tekken map and some random page where all the buttons are blue and the digital readout goes "-". I have difficulty returning back to the Native mapping so I can control the remix decks natively. Am I doing something wrong?
