It often depends on the unique id, some shows have a "unique id" that doesn't really identify the show. As an example the real unique id of the show "The Americans" is EP01616980 plus the episode number. For me sometimes the EPG uses a generic SH016169800000 that could be any episode. When it ends in 0000 you can't delete it. These are usually easy to tell because they don't have valid subtitle or good description of the show.
