Image changes on export, when flattening all layers or merging all layers.
I want to export this image in Photoshop 22.5:

When exporting everything seems to change. I tried playing with the export settings, but this wouldn't change anything. Merging all the layers or flattening the image results in the same as the export preview.

I think it's because two of my layers are using the luminosity blending mode. When I remove the two layers my viewport and the export will have the same result again.
Has anyone any idea what the problem is or how to fix it?
Already, thanks in advance!
