Hello Michel,

I applied a fix to your website. The issue was on the grouping of the fields thats why you could not see it in the editing of landing pages.

Let me know if you see the error again.


Thanks Konstantinos,
Yes it works.
Did I do something wrong to have this issue ?

No you did not. It is a configuration issue that the Easy Start template had so you got it from there.

Good that you mentioned it because I fixed it in the template too :+1:


OK, good news.
