Unable to Delete "Item" from Imported Collection

After using the command dopusrt /col import /create /nocheck /clear /utf16le "Imported" "C:\Playlist.m3u", trying to delete the #EXTM3U item that was added to the collection was not possible, either with Delete SHIFT or Delete REMOVECOLLECTION. The error message was "An unknown error ocurred".

Deleting other invalid items with proper path was okay.

Maybe strings that aren't a proper path should not be imported?

Thanks for reporting this! We've fixed it for the next update.

Also note you can remove /nocheck from your command line to avoid adding items that don't exist.
