GCS - Finding Files stored in wrong storage class

[LC11]

Using the monitoring system in GCS I can see that I have 1TB of data in 'regional' storage class while 7.5TB is in 'archive' class.

Using CyberDuck 'info' panel on the folders, and checking all the top-level parent folders, every folder 'seems' to show as 'ARCHIVE' storage class. So how will I ever be able to know where the specific 1TB of files are (ie which files/folders are seemingly in a 'regional class' while their parent folder is 'ARCHIVE' storage class?)

I can confirm that in the attached image both project_id's and bucket_names match for the two image classes a shown

Thanks for any advice.
