iTunes Showing Multiple Copies of Audio Books in Grid Display

I have a number of audio books that are broken into multiple files. Some are separated by the discs others are broken into chapters. After one of the recent updates most of them are now appearing multiple times in the grid view. When I switch to list view on the one book is listed. When opened each copy shows all the files that the book consists of. I have tried some of the fixes online but nothing seems to work. Is this a bug? If so how do I report it? If not how can I fix this?

This is iTunes 12.8.0.150 on Windows 10 Home 1803 Build 17134.254
