Upload space full?

Hello, I got an email saying my upload space was almost full, so I deleted one of my 2 forms and half of the submissions from the other one, and it's still telling me my upload space is full? What is wrong? I only have one form with 13 submissions currently.

Thank you for contacting JotForm Support
It shows on our system that your Upload Space was at 92%
This is the submission of your forms.
to be able to continue and avoid losing some documents
we suggest downloading your submissions before deleting them
