My issue is resolved. I was behind 2 versions of the PVR addon running version 2.0.1 . The bug was fixed in 2.02:
v2.0.2 (2019.05.08)
- Update SQLite database engine to version 3.28.0
- Prevent multiple Kodi threads from simultaneously requesting EPG data
- Prevent individually malformed EPG data request results from aborting all remaining requests
- Fix bug that allowed extraneous EPG entries to be transferred to Kodi
- Fix bug that prevented successfully setting channel visibility flags
- Fix bug in database layer that could cause unhandled exceptions processing NULL column values
I've updated to 2.03 and the issue is resolved.
