Light turning on constantly in rain on pro cam

I have 1 floodlight cam wired pro and the light is constanly turning on when it rains, I have a number of floodlight camera wired plus in the space and they work just fine and are brilliant.I have tried tweaking the settings to no effect and have put a light schedule on to turn it off to stop the neighbours getting upset. But totally defeats the point of having a floodlight.Any ideas how to fix?Ideally a swap for a plus would solve all my problems, hoping ring would consider that. I thought the pro was meant to be better but not what I am finding sadly.
