3-way switch positions

last month

I have five 3-way switches in my house. IE, two switches controlling a light. For four of them if both switches are up, or both are down, then the light is off; if they are in opposite up/down then the light is on. For the fifth set, though, it is the opposite; switches in opposite positions is off. The switches are all passle switches with the manufacturer name on them, so I know they are all installed the same way up.

Is this anything I should be concerned about electrically? Would flipping the two wires on one of the switches change it, or would the wiring at the light need changed? House was built in 2019.
