Strange color issue on the playfield of Stranger things 4

[tonybobo]

Table looks and plays fantastic, will definately be one of my favorites! I am having one odd issue though, whenever I enter the upside down the lighting turns this weird blue and I cant tell which targets are lit. The playfield almost looks like a photo negative. I thought this was just a feature but I saw a gameplay video on youtube that didnt do this. Is something wrong with my setup and if so do you know what it is? TIA
