Hi!
I'm not sure if it's right place to ask my question but I have an issue with merging rasters.
As you can see in the first picture, I have 4 independent layers with symbol 0 having no color.

Using "Mosaic to new Raster" is doing something like this:

Mosaic to new raster window:

All I want to have is to just merge those rasters into one file and have symbology like in first case.
Any suggestions?
