Channels Not Rebuilding 0.5.1t

Hi,
Just an FYI.
Installed Version T today. Updated from 0.5.1g. After doing this and doing a clean start from the Utility Menu, the restored channels would not rebuild.
Installed on a clean build of Kodi and created completley new Channels and evreything built fine. However, doing the Clean Start again and restoring the new Channels, they would not rebuild.
The Channel setting shows the number of Channels listed as there, but entering into Channel manager they are blank.
At a guess, Im thinking that PTVL thinks the channels are there, so it is not rebuilding.
Thanks
Oz
