Upload space still the same even after deleting uploads

I have just deleted lots and lots of my form submission to reduce my Upload Space but it hasn't made any difference, do I need to wait a while for this to update and for my forms to become active again?

I checked your account and I saw that there are still forms in the Trash folder. You need to Purge the forms so that the submissions on the deleted forms will be not be included in the Upload Space counter.

Let us know if the issue is still the same. Thank you.
