The one thing I can see that might be an issue is that your filenames don’t exactly match the track titles on MB. Try removing the ( 2021 Master) from the filename and see if it makes a difference. I’ve had issues that were solved by this in the past.
Note: When you rename files, you will probably have to do the “Plex Dance” for the album. They’ve eliminated the need for this step in most cases, but renamed files is the one case where it’s still necessary.
I just noticed your files are in wav format. That should be fine, it’s a supported format. I just have no experience with it, so I don’t know if there are any specific problems related to it.
