After further testing, it appears that GameEx is treating anything pure black, even semi-transparent pure black objects, as 100% transparent. This is occuring not only in foreground .bak files, but also in logo files where there si a pure black element. This then causes the background image to show through. I am going to try using a "near" black to see if this remedies my immediate issue, however, I don't see why pure black cannot be used. EDIT: My assumptions have been confirmed. Near black works.
