Thank you Page not working

Hi there. I just finished testing my new form and to my bad surprise the thank you message I setup through gravity doesn’t show! Instead it shows a random message from Typeform https://goo.gl/hmSihL
Moreover the last entry tried does not even show up (another user reported this problem here)

I was excited about this plugin but apparently the front end is the only thing that works fine, the entire backend is full of bugs.
