Importing MetaInfomation from CSV file

Hello,
I took a look at the pinned Mass Import from CSV file thread and am running into an issue importing MetaInformation into the RDMSession that my script is importing. I have the following script, mostly copied from the pinned thread, though modified to use updated cmdlets. In testing, the script will add the two servers I have in the CSV file, however when looking in the properties panel, none of the metadata is being populated. I've tested to make sure the script is properly getting the information and looping through it. I do see in the Powershell window WARNING: Connection not found. So I'm wondering if its not properly finding the GUID of the $ServerEntry variable. Using RDM 2020.1 currently. Any thoughts?

Edit: I notice that if I try to access the RDP session in RDM with my imported servers, they won't work unless I open Properties>General, and populate the host by clicking into the Hosts field where it autopopulates. Could this play into the issue?
Edit 2: Added a -Host to the $ServerEntry variable definition to get around the Host field missing. Seems that is not the cause of the metadata issue.
