Duplicate albums?

I have a eversolo dmp-a8 and prior dmp-a6, both have issues showing duplicate albums (4 of the same album) in the library. I am not looking to categorize them as a work around, rather resolve issues. I have cleared cache, removed library, rescanned. All same results using my external nas storage. Same issue occured with internal ssd on my dmp-a6.

Any fixes? Thank you all for your support
