Trying to send free Fill and Sign Document

I am trying to send a "fill and sign" document.... for a rental contract.

I accidently chose the wrong dates (did 2020 instead of 2021) and did "Fill and sign" and sent it to my email address, before it went to the tenant.

However, I caught the wrong date after I signed.... and so i changed the date on form and sent another one. It never came through to my email, at all. I dont know why. I tried again, and it said "You dont have anymore available without a subscription". 

I was able to cancel the first two signed documents... and then in top right hand corner it now says "2 left" before upgrading...

But as I filled it out, and tried to send.. it still wont let me.

I am not ready to get a subscription yet.... what do I do?
