How to Fix Google Folder Trigger Not Saving for Agent Automation

I have an agent that I want to trigger when a new file is put in a specific google folder. I keep saving the configuration and choose a specific folder in the attached screen shot. It seems to save the Folder but then seems to forget it. The agent is not triggering properly - I think because of this. Is there a better way to set up this trigger? Or is there a fix so that it saves the folder location permanently? Many thanks.
