What exactly do you mean by 'force update addons in the menu on the left'. I can select Update in the config for the add-in, the only version available is 9.0.118.
I tried a new install and everything is fine (TVHeadend 9.2.110) so it looks like something went wrong with my upgrade from 9.0.2.
I will carry on with the new installation and see if I can copy the TVHeadend config from the old system.
