The gray block next to the tailplane on the parts kit is supposed to be glued to the top of the lower wing. It's slightly narrower than the space in the lower wing top so it should pull the wing's top together, locking in the dihedral (sort of). Seems like you may have missed attaching that part. So at this point the only thing you can do is make sure the upper wing is stiff enough to support itself and the dihedral of the lower wing, and when you attach the wing to the struts, ensure that the outer struts don't reach until you add dihedral to the lower wing. You may need some CA to get it to hold tight.
Or, you could engineer the model like the actual plane and set some rigging to hold the dihedral in place. :p
