Latest Excel Office 365 ProPlus cannot recognize DateTime correctly and sort DateTime correctly

Hi, 

I updated to the latest version of office 365 ProPlus. The problem with this new build is that it does not sort DateTime columns properly. It just recognizes them as text. I did not have this issue before. I did everything I could think of but could not get it to work. I would be happy to revert back to a previous version if this is not fixed soon. Any ideas?
