The change of the 12th June 2019 which you mentioned Help affected these channels - the table below shows the old and new channel numbers
The guide data has not been updated to accomodate for this recent change and this was referred to our development team.
You should be able to override this by manually mapping those channels to the corresponding guide channel numbers
If any channels are no longer listed by the tuner (list on left before any mapping), then it is possible that there was a frequency change. If there has been a frequency change, please let me know what it is and the exact name of the transmitter.
You can get the frequency from the detailed channels view when tuning all channels within the WinTV app
