LED Light gremlin

Hey everyone

I've got a gremlin. I replaced my lowbeams with some JW Speaker lights, and my high beams with United Pacific lights.

With low beams on, and high beams off, all 4 lights come on, and with only high beams on, my low beams then off.

Before you ask, I've tried every different way of rewiring them, changing polarities, and nothing seems to have fixed it.

Truck is a 2018 4900EX

Thanks in advance for your help.
