The setting you are looking for is in the ReflectionSettings named ReflectingAmbientMult I hope, if not there is a separate setting for spot lights (ReflectingSpotLightMult) and this is caused by the spot lights having their ambient set to a reddish color.
Configuration for the other stuff you are missing can be enabled by switching reshade into config mode in the Settings tab.
