I am working with windows 10 pro 64 bit with Affinity Photo version 1.9.1. I was following a Youtube video creating realistic lipstick and I get to the point where I am on a fill layer and I click on the cog wheel next to the blend mode tab and move down the first dot to blend the layer and it does nothing. no changes happens, it stays the same as if my lipstick is still painted on and not blending in like the video . I have an attachment of what is happening to mine verses the video. I have tried three times and I get the same result doing every thing exactly as instructed and so I am not sure if it is a setting that is incorrect and not allowing the blend mode to work properly or what the issue is. I am needing so help understanding the problem
