Hello I have an existing creator app with a bunch of form data.  I want to create a new report in the spreadsheet style.  I'm able to do so, but in the view report I can't edit any of the cells and this little red * shows up at the top of the report.  I click save changes and this is what it says.  

I also have tried clicking Revert Changes, but that does nothing.  Why is it automatically trying to change the view type from XLS to List??  I tried creating a brand new form and the  spreadsheet report worked as expected.  How come I can't make a proper spread sheet report from my Existing Data?
