There was an error loading the banners: Cannot read properties of undefined (reading 'toLocaleLowerCase')

Getting this error with Azure DevOps Server 2020 when clicking on the banner extension:

"There was an error loading the banners: Cannot read properties of undefined (reading 'toLocaleLowerCase')"

It allows us to create new banners successfully. However it will not list any existing banners.

We were using the Azure DevOps extension for Azure CLI prior to getting the banner extension from the marketplace. Perhaps could that be why it is throwing an error? Does it not like the older banners?

When we run the "az devops admin banner list" command, everything looks fine. No issues listing all the banners.

We do notice the banners created from the extension show an ID number added to them that starts with "p2-" followed by a 13 digit number. (The banners created from command do not have this.)
