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

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 
Have you rescanned your music library? If the files are not on your NAS they should not show on the app.
