Alpha makes the image underneath darker

So I'm using some Logos with an Alpha channel on them and using them makes the image underneath darker, I found an older post which mentioned this as well

Is there something in the settings causing this? I know Resolve is weird with images and it's scaling but I'm not sure if there's a way round what's happening here

Figured it out -

Clip Atrributes - Field dominance - Upper field

Such weird things with this software
