Emails from displet don´t get added to aweber

I have installed Displet to have pop-ups on my site and also installed gravity forms to add use in conjunction with it. I also inserted the aweber code to gravity forms so that these emails would be added to the mailing list.
The problem is that I have gotten emails through the pop up and these email have been listed in the gravity forms section but these emails have not been added to the mailing list.
Does anyone kno what is going on and how to solve this?

Thank you
