***I think I have found the way to solve this problem! Now I Can tell you how I have made.
instead of setting the entry to the funnel by module on sending blue, I setted the option to find a dedicated list.
In Sendin Blue it is not explained in the guides, so I had to get there by tweaking a bit, setting the option that when
they choose to subscribe to that list they enter the funnel.
Because usually the option presented is the module, and therefore you don’t get there right away. In the options after looking there is also this.
So the problem is solved.
Thanks anyway for any help that you have given to me.
