Problem with pixel + events

Hi, im running 2 campaigns on the same domain

1 to the home with one "contact event"

other to an inned page, when i need the submission of a form, i select on the events "potential client" and i set the button

but when i create the campaign i see the message this events isnt configured for this domain

but i already do that

i need wait or im missing someting?

thanks !
