File deletion does not increase space available in CC

I did an experiment this morning to see what was going on with my space utilization being incorrect.

1) I added about 5GB of files and folders to my local CC Files folder

2) Sync worked properly, my utilized space went from about 5GB to about 10GB

3) I deleted 5GB of files and folders from my local CC Files folder

4) Sync worked properly, and all 5GB of files and folders were archived in CC

5) From the website interface, I deleted all 5GB of files and folders from the archive

6) My archive showed as empty via the web interface

7) My files and folders on the CC web interface matched the contents of my local CC Files Folder

😎 My CC space utilized, according to the web interface, only dropped from 10GB to 9.2GB, but the actual utilization should be a little over 4.9GB.

I suspect this is happening to everyone and will get worse with time. Adobe - please address.
