I can not get rid of the large list of configurations, which turned out during training. On your advice cleared Editor with red X according to the scheme: Open yEd > New Document > unnamed0 > Edit > Pr. Mapper - list is absent.
But as soon as I open the file Excel or the saved configuration for it, this list is again present, reborn as a phoenix from the ashes ...
How to proceed? What I must to do?
