Look at the addon settings.
You can localize a lot of stuff and also disable any background actions in the section 
"Download TV information"
Set both settings to off.

I have TV Show - Next Aired 7.0.1, if I open its settings I only see a Program section, and it doesn't have options to disable anything... I guess it's because I have MarcelVedt beta repo installed. I'll see how things evolve, many of these add-ons (like Artwork Downloader) look a bit unmaintained (for obvious life reasons). 

Yeah, that's it.
I use 6.0.15, which works perfectly.

I have added that version to my repo.
Install that and disable automatic updates for that addon.

In 6.0.15 you'll have the mentioned addon settings.
