Weird purple tinge color on night vision

hello I bought a Ring wired doorbell from amazon UK and on night vision / (colored nightvision) I am getting a distracting purple tinge of color from vehicle headlights going down the road and people’s faces approaching the doorbell and reflected off car registration plates and reflective signs - could this be a fault with the doorbell? - I have been on a FB group and they said it looks to be faulty something about a filter or something. Here are some night pictures from it - pretty bad quality, bleached out over exposed face and purple colors : Face overexposed and purple tinge to face and hair - reflection off car registration plate purple!
