Data Manager shows 2 duplicate DataSets (both with the same name and same symbols). If I delete one of the duplicates in Data Manager, but when I open Wealth-Lab Pro the next time, they are both there again. I can rename one of them, and that change is permanent.

When I go to C:\Users\[User Name]\AppData\Roaming\Fideltiy Investments\WealthLabPro\1.0.0.0\Data\DataSets, there is only one .xml file with that name, and the renamed one doesn't appear at all.

Is there some way to delete the duplicates from the list that appears in Data Manager?

I have relocated my Fidelity Data to a different drive if that makes any difference.

File name can be any. It's only the <Name /> tag that matters. You can make a full-text search inside the DataSets folder to find the resistant XML file, for example.
