Queues app shows GUID instead of queue name

We have an issue where queues app is displaying guid instead of the queue name in the queues app under agent data or the list under calls answered by agent. Have cleared cache and reset teams as well as made sure client is up to date. The cache clear/reset actually made the app not load any data with a “we cannot load the data right now” error for about a week then started randomly working again but with the guid issue. Anyone experience anything like this?
