I've noticed that mobs that are behind objects of the same layer are rendered behind the obj. How does this work and can I change its behavior because I have some layering issues with large icons.

Place the icons you want in front on a higher layer will fix your layering concern. Atoms on the same layer can produce finicky results. Alternatively, you can research planes and accomplish the same thing and possible save time in the long run.

My projects for example have planes specifically for backgrounds, foregrounds, effects, etc.
