How do I delete albums with the Bluesound OS app

I have a Bluesound Node 2i. I have a NAS drive. When I delete my CD's from the NAS, they do not delete from the Bluesound App. I replaced a lot of CD's that I converted with Apple Music to using DB Power Amp for better conversions. I now have duplicates of everything in Bluesound. I would like to delete these files. Thanks
Have you rescanned your music library? If the files are not on your NAS they should not show on the app.
Good idea. In BluOS go to settings... Reindex Music Collection.

I figured it out. The solution was in my NAS drive. I found a trash folder and once I deleted the files all the duplicates and triplicates disappearedĀ
