Disappearing Posters and Fanart?

Dear all, It’s been a year since I got my Nvidia Shield (Android 6.0) TV. Kodi 16 was the first application I installed (In it’s internal memory) and had been using it daily without any issues. Everything worked as it should, all my movies, music, pictures scraped and play backed fine. ‘Till’ I decided to try out Kodi 17! I thought of starting fresh, so deleted Kodi 16, the library and Installed Kodi 17. Added the files from my network hard drive, scraped them and viola! Now none of the file’s posters or fanarts appear anymore Sad One or two, briefly appear for moment. But then disappear leaving a blank rectangle placeholder. I have deleted and re-added and re-scraped the shares multiple times now, same result. Re-installed the app and even tried deleting the textures.db file to see if the images appear, but no luck. What could be the issue here? Shouldn’t have messed with something that was already working.

Edit: I have deleted all the .nfo, .jpg, .png and .metadata files from my network drive before adding them to Kodi again to scrap, didn’t work either.
