Ah, I think what's happening is that you're using the "designer" to create your grid. When you do that, it saves LOTS of data to describe the grid, including perhaps the color of each cell, etc.
What I do is programmatically create the grid and make API calls to set the colors, fonts, etc. This removes the need to save data describing the grid in the resource file when it's compiled.
Unfortunately, this may take a lot of work on your part to change at this point, but I hope my explanation at least helps you to understand why it's happening. ;-)
