Project->Compute->Overview shows wrong RAM usage


I am not able to instantiate any images because OpenStack thinks I am out of memory. Under Project->Compute->Overview it shows 50GB used out of 50GB. The 50GB value is set in Admin->Defaults as 51200MB. I have one 'cirros' image running that has 4096MB allocated to it. Under Admin->Hypervisors it shows the physical host is using 28.1GB out of 96GB installed.

Using the 'free' command I confirm the 28 used out of 96 is valid. The 51200 limit is valid, but I have no clue why it believes it has reached that 51200MB limit.

Any help in what to look at / for, is appreciated!
