I'm having a partial success trying to fix this. I just got the latest version of CFSM (v1.2.7.9) and ran the repair with the Add DD button selected. http://imgur.com/a/cV1Yt Good News It did a great job fixing the songs that did not have DD. They now have DD, the 100% bug is gone, and no chord clutter problem. Bad News I'm having issues with songs that already had DD. It did fix the 100% bug, but I still have the chord clutter. http://imgur.com/a/uCn6m The example above is Lola. I also tried going to the song manager tab and using the bulk action to add DD to fix it. No luck TLDR: The current fix in CFSM works for songs that do NOT have DD. However I can't seem to fix the chord clutter issue on songs that already had DD.
