Why is it displaying 'Out of submission limit' message?

I got the message after logging is: "You're almost out of storage limit".

So, I've cleaned (deleted) a substantial number (± 95%) of the submissions. However, logging out and logging in again keeps showing the message: you're almost out of storage limit.

What am I doing wrong?

I have recalculated the submissions storage of your account and the submissions count is now reset correctly. Please check and let us know if you need any further help.

Thanks!

Thanks very much.
The message has gone.
BTW: the form ‘Mobiel NL Aanvraag B&B” shows every time I login a ‘new’ submission and a total of 4.
Clicking on the form only shows the old submissions and not a new one: the total number is 3.
Logging out and again logging in, again shows the mystery submission: and a total of 4.
Strange
