With this new site, you likely still reading off the cached version, so the usage you got was not up to date
An easy way is to click the Spinner on the bottom right of the section to force a refresh.
If you don't see an updated usage still, try to login My Account using Incognito mode (or InPrivate for Edge, Private for Safari) or try again with a completely different browser like Edge/Firefox/Chrome or try on another device. You should then see the latest info from the server.
