I cannot find any reference to this issue in 4.7.7 mentioned here. My "Repeat Event" tab appears different than in test - with additional options.

Situation: As expected, there should be an enforced error check between radio buttons "Repeat Weekly" and "Repeat By". Repeat Weekly is once a week or once a month or year, etc. Repeat By could be Every Other Sunday or First Sunday, etc. The two options are mutually exclusive.

HOWEVER - the error check is looking at the two options within "Repeat By" and ignoring the fact that Repeat Weekly is selected. It throws the error that I must select one option (see attached pic) in what appears to be the Repeat By section.

FURTHER - when I select "Repeat By" and hit Save, despite what appears to be a successful save, IT IS NOT SAVED. No errors. No repeating event confirmation. And the tab is cleared

Thanks
