Problem adding rasters

I am trying to simply add two raster with the "plus function" but the result is not correct. I checked the results pixel by pixel (randomly selected a few) and sometimes the sum result is higher than it should be and sometimes it is smaller. Does anyone have a solution for this?

Thanks in advance.
