I have run into a funny issue.   I have noticed that while using Firefox, the program does not work correctly.  A large portion of the entries get placed into the wrong section.  With a little digging, I discovered that this is a Firefox-only issue, because of the May 25th update to the Official Sheet. "Layout fix for Firefox versions 87+"

The tool is working great, unfortunately, R20 has done a switcheroo on you with the sheet layout, making the tool unusable in Firefox.
