Lumin tag view makes me double folder

[The Legend]

Hello to everybody !!

I have minimserver perfectly working but I have the following problem on Lumin, I use always the Folder browsing to sort music as I like and when I'm in the Tag View I have always two folders that have exactly the same details when you click on the folder (same album, tracks, artists etc).

I checked even on my pc and the library also has no double folders so I don't know what to do to eliminate one.

Please help me to know where is the problem .

Thank you guys !!!!!
