Hi,
First of all thank you for installing our plugin.
I would be glad to help you resolve this, can you please let me know the following:
Version of your WordPress, Version of CF7 and the theme you are using.
And, when you say you are not able to do anything with the two you have created, do you mean those are not showing in the dropdown?
Tip: Any form starts showing up in the dropdown only when there happens at least single submission. So, if it is not showing up in the dropdown, try to just submit one dummy data in both those forms from front; and it shall start showing up. The reason why we did it like this is because we didn’t want to show forms which are not having any submissions.
