Need someone to fix Add on "Send to Third-Party"

Hello,

I have the Add on Send to Third-Party, wich sends datas collected by a form to a server. This used to work, until a week ago when it worked once in a while, and now it has stoped working.

One thing strange : the flows that were already created are displayed in double as you see here https://www.screencast.com/t/dJcmvPXx.

Then I tried to create another flow, but without success.

I need someone who knows to fix this asap.

Thanks in advanced.
