A little more information about what changes you are making would help in understanding what is going on.
Generally, the program works on a model which uses the brew house efficiency to determine the amount of sugars which make it into the fermenter. Changing any water volume except for the volume to fermenter will not change the values at all, as the program just recalculates the amount of sugars extracted from the mash.
The calculation of color and IBU is similar in response.
To elaborate a bit on how the program works. It calculates the water needed for the brew. You can enter as much or as little water into the recipe and the program will still default to the calculated values. All calculations for gravity, color and IBU are based upon the calculated values for volume.
