Every album imported is duplicated

After updating to the new version of Roon, albums I had imported the night before disappeared. I went into the setup menu and entered the location of the music files on my computer again. I was thinking it would find the missing albums and import them; however, what I ended up with were duplicates of every album! It has continued duplicating each new album I add, so I have no idea how to resolve this issue. I would greatly appreciate any assistance.
