disk space limit calculation on accounts

i have about 20 accounts on my server, all setup with disk space limits, but when i look at them on the web portal, it doesnt seem to calculate the disk space used by these accounts, from memory it use to, but not anymore, any idea why?

Sorry, I advertise my hosting as "No More Tiers" (a play on Johnson & Johnson's Baby Shampoo). So I don't have any disk quotas in place. I only have 2TB SSDs in play , so any hard limits are still years away for me. But the "More details" hamburger menu seems to accurately list the SQL DB and mail usage under the Accounts list.

hahaha
