Powershell script to load data while setting managed metadata into Sharepoint list

I wrote a script to read data from an Access db and load it into a Sharepoint list. In my script, I set columns defined as managed metadata based on values in the Access db. Everything looks great in Sharepoint.  However, when I try to retrieve it in a PowerApp, the data is not displayed immediately.  I have to into Sharepoint, retrieve the row and hit Save - note, I do not have to change any data, just simply hit Save and the data is available in my Powerapp. 

I'm assuming there is something wrong w my powershell script.  Any thoughts
