Bump map changes after Saving Layers

Hi guys

I`m learning Blender and so far I love it. I have a problem tho when I paint bump map. It looks as it should untill I click Save Paint Layers (addon: Texture Paint Layer Manager).

It changes to something like this “layerish” thing:


Do you have any idea how to tackle this?

It was because I had 8-bit PNG set in Rendering options and Blender saved it like that.
