LiveTV | Channels suddenly randomly sorted

A few days ago (before the July update) the LiveTV|Channels list became randomly sorted. Channels no longer appear in order of numbering. The LiveTV|Guide view is still sorted according to channel numbers. I’ve unchecked and checked the settings about whether to use remote channel order and numbering. The original issue may have been duplicate channel numbers on TVHeadend. By now that has been fixed. How can I restore LiveTV|Channels sorting by channel numbers?
