Some foreign key doesn t work - mysql

Question

I am trying to create a data base withe relation ship. So with PHPMYADMIN, I use the conceptor mode only for my relationship. So I see that my differents table are linked. But when I export my data base, I see that relationships are broken except two or three. I dont know why. I tryed to with sql code but its the same.
relationship who works :
after export
that I want :
before export.
In this picture it is all the relationships that I want.
but if I do this code
ALTER TABLE `personnel`
ADD CONSTRAINT `personnel_ibfk_1` FOREIGN KEY (`idDroit`) REFERENCES `droit` (`id`);
I have no error but in the conceptor mode there is no link between tables.
here my sql code : (it s a french table , sorry ...)
