Shared folder Not Syncing with Coworker

I have shared a folder with a co-worker. I have a 20gig limit and they have 2. I filled up that 2gigs in that shared folder and it stopped the syncing. So I started deleting/moving folders and files out of the synced folder. The computers do appear to reflect the changes I made but the app still says that she is out of space and to clear out some space in the archive. But there is nothing in the archive.

Her error shows "There was a problem syncing some Files... You are out of storage: Permanently delete files from the archive to continue syncing. View Archive". But there's nothing in the archive that shows up. Most of the files weren't deleted but just moved out of the folder. I did empty my archive folder as well. I've also stoped syncing and restarted from the preferences in the cloud app.
