Powershell returns no sessions even though current data source is correct.

I don't know the steps to reproduce this. It appears to be random at the moment.
I have a script to create entries.
The script prompts to enter a name of a company.
It then performs a -like wildcard match and if it finds a match it uses that company as the parent group.
If no match is found it creates a new company using the name entered.
Some times it fails to find a match even though there is one.
I Stopped the script and ran some commands in the same powershell instance to troubleshoot

get-rdmcurrentdatasource to check it was using our SQL data source

it returned the data source correctly.
I then ran get-rdmsession and it returned no results even though there are a lot
any idea what could cause this?

I have just installed the latest version but this occurred on 12.0.8.0

thank you
