When my main preview window game source is causing my head to b faded in with the same source window

Hi everyone,
i previously posted a forum on this topic a while ago and whenever i choose a game under sources my upper body and head seem to fade away with the main preview window of obs. I had this problem before and it just doesnt look right that way. I have tried to make a smaller window within the preview window but it doesnt seem to help the issue really. I dont know how to do this correctly if theres any kind of filters or adjustment on the settings within obs. if someone could please give me some info on how to resolve this small issue i have with it itd b great thanks again.
