Error in Document Generation object "Failed to retrieve Document Generation consumption..."

Full Error: Failed to retrieve Document Generation consumption. Try closing and reopening the action to refresh the connection.

I have followed both options found here but still happening: https://community.nintex.com/t5/Technical-Issues/Failed-To-Retrieve-Document-Generation-Consumption/ta-p/84520

We have just activated DocGen for first time and have never used it before.
