Sharepoint user profile no longer pops up on user columns in lists

Our Employee Directory is a SharePoint list in gallery format with some custom JSON formatting. After our tenant has switched to the new List format (with the views tabbed across the top) our "person" column no longer shows the Sharepoint user profile card (attached a screenshot of it, in case I am calling it the wrong thing)... which is where all of the contact information is. The SharePoint user profile cards pop up fine on the "person" web parts used in page content. 

I've tried resetting to the default view in case something changed related to my JSON... and tried another list on a different site on the same tenant... but that doesn't help either. 

Is anyone else having this problem? Anyone know how to fix it?
