Missing metadata- API problem?

Hello,

Regarding the above mentioned, just to check if my system is faulty or is it really just the API issues – I’m using Kodi 17.3 and I have TV episodes in my hard drive. Suddenly some (but not all) data started to be scraped with missing information. Sometimes all the information is missing and all I see is just an episode number (although it does show in the TVDB) and sometimes just a photo.

My temporary solution is to update the information manually.

What do you think it might be?

Thanks for any answers regarding this.
