Example Human skin and ambient occlusion?

I have a strange issue… i took the example human skin that is in one of epics learn projects… and i added a texture for ambient occlusion into the materiall… welll this is the result… Any ideas? And no… there is no black on the nose in the AO texture…

Is there a solution to this?

Ok now i literally for testing purpose removed the ao and put a scalar on… of which 0 ao didnt work but i thought whatever… reconnected the ao map… and now the results for ao are different…

Is this a bug?

Never mind found the issue… the texture was being imported as a normal map for some reason.
