Did you look at the switches and make sure the leaf orientation is the same as what you replaced.
It might look like it's wired correctly. But if you examine the switch itself. And the leaf blades, and how they are positioned. Is it actually wired correct.
I've had this on replacement switches. Where it looks correct but actually physically wired to the wrong blades. Where it's a normal open switch. Wired from the factory to be normally closed.
