Channel Numbers from MythTV backend not working on Android

FWIW, channel Numbers and grouping from MythTV backend does not seem to be working on Kodi 17 Android but is working on Kodi 17 Ubuntu Linux install.
I have several Android boxes showing the same issue and several linux boxes that are just fine.
I’ve made sure that the settings are the same on both boxes.

I have two HD Homeruns feeding the MythTV backend.

Note: I fixed my problem by wiping the Android installation and setting Use Channel Numbers from backend before enabling mythtv pvr client.

I suspect the problem is that Android Kodi does not properly clear it’s settings and data when the channel groupings and numbers are changed.
