Previously (with the same identical result) I was using only the "." option because , in theory it look like a wildcard selection that would show any format of any image that is in the folder (first image listed in the folder)
The problem persist, I have 2 problems
1) some albums refuse to show album cover
2) some cover art keeps reverting back to the second picture listed in the folder instead of the first which is the album cover
I did create a new library just in case, problems have not changed
