new shows not being added to library

I can post logs later, here is my issue in case it rings a bell with anybody..

Ever since upgrading to Kodi 17, new TV shows and movies are usually not added to my library. Even if I force a manual update, they are not picked up.. However, if I remove the source and then re-add it, everything new is picked up (or if I set the scraper to none, let the library clean out, and then set the scraper back to TV and update the library, all my updated shows are now present).. I’ve seen in the logs messages about skipping folders (where I do have new shows) as no changes were detected, so the folder was skipped. I’m not sure what to do to get around this…

Any help is appreciated.
