Try rebooting Kodi and or reinstalling... Also maybe try deleting PseudoTVs setting.xml

Deleting the settings.xml allowed me to add channels, which were then getting built but not showing up in the guide. In the end, I deleted the settings.xml, the PseudoTV guide data and M3U file and everything was sweet once I created the channels again.
Not sure what you did with the last update, but all of my channels are now switching lightening fast!.....Oh-La-La-La-La!
Happy Days!
