SharePoint- PowerApps Multi-Select Cascading Dropdowns not Saving All My Selections

I have the same issue. I can get the values for the cascading dropdowns to populate on the custom PowerApp form when it's saved back to the SharePoint list.  However, when we go to reopen the form, those values are blank.  The values are saved in the list, just not visible on the form when opening it on View or Edit.  I've tried using the dropdown inside the datacard and using a variable to populate the text box of the data card based on the dropdown selections, and moving the dropdowns outside of the form on the main canvas and it still does the same thing.  This is so frustrating. Any information on how to make those values stick would be appreciated.

These are the fields that populate the list:  

 This is what we see when we reopen the item to view the form: just empty text boxes

HELP!!
