I have a SharePoint Online list using the Modern view that I have grouped by a date column. When showing the list of groups everything appears fine. However, when I click the group header to view all of the items for that particular date, the date format is butchered, which causes no results to appear.
This seems to happen on all of the SharePoint lists that I have tried this on, which includes two separate SharePoint Online environments. Is this a known issue? Is there a way to correct the formatting so the results are shown?
The regional settings are English - United States. The same thing happens regardless if the column is a Date column or a Date/Time column.
Screenshot of grouped view - date format is correct and two results are shown:
