I have a rip of one album ( Pierre Monteux/LSO, Debussy various works). I have replayed this via JRiver 20 and 21 many times. However last week I opened it , played track 1 and then closed it. The next time I tried to play it I noticed that the cover art was appearing twice instead of once in Album view. Opening each instance I found that one contained tracks 2 - 8 and the other only track 1.
I have checked the music data file on my drive for this album, and it appears only once with all 8 tracks correctly stored. I therefore deleted both of the instances in JRiver , closed MC and then re-opened it to allow it to interrogate the drive and re-import the album. However, despite my earlier selection, once again two copies were generated in MC 21, again one with only track 1 the other with the rest of the tracks.
Next removed the drive to make sure that MC was not re-importing the album before closing after deletion, deleted the albums(s) making sure I selected the permanent deletion option. I also deleted the album from the drive and re-imported a clean copy to it. Then I re-attached the drive to my server computer and re-opened MC. Once again the dual inventory was created with track 1 on one and tracks 2-8 on the other.
Any suggestions of how to solve this?
