Duplicate Album folders Unitiserve SSD

Good afternoon all.
This is my first post on the site. Apologizes in advance if this has been covered before. I have a unitiserve ssd with a drobo 5n Nas serving 4tb of WAV.

I have noticed that there is no coverart coming over at all I assume this is because it is WAV also the Unitiserve is creating multiple duplicates if the same folder example the Beatles 15 albums in this folder populates 5 times on the naim iPad app and on the online host application. Finally and I apologize for so many questions there are some tags that were created correctly however do not populate correctly example again the Beatles for artist Revolver for album populates as 2009 remasters. Which is a comment I added when I ripped using Max. I have an all MAC set up.

My thanks to you all for guidance you can provide.
