Issue with Kodi 21 Showing background pictures for Movies



I recently upgraded to the latest version of Kodi (21.0 Omega) on my Android Media Player. Since the change, I can no longer see any of the background images for the video files I have on the two external hard drives that I have connected to the player. I have previously downloaded posters for all the TV Shows and movies and added these to the folders on the drive and they are all viewable in Picture mode, but when in Video mode, the posters which previously were viewable with the previous version of Kodi, but now only show as a blank folder, without a picture.

Does anyone know a work around to display these images again. I took ages to add all the images and it looks better when you are scanning through the folders to have the images their in the background. I would appreciate any assistance anyone can provide.
