CC Storage Full. Deleted Files from HD. CC still full?

I put some big files on my C drive in the CC Files folder. It filled up the file size of the storage which was fine. I didn't need it synched for mobile. I completed what I needed and deleted it from the CC Files folder on my PC. But I've tried to get the CC app to recognize that my CC files folder on my PC is only 20GB now, but the mobile version is still "full".

Shouldn't the app look to remove the files from the online folder and then continue with synching or does it make a hard stop when it's full and you have to manage the files online before it will continue to synch again?
