Why doesn't a second element's simultaneous decrease in concentration appear to affect the examined element's proportionate increase in concentration?

That second element, which I assume is [C], has no effect on the initial rate, so it is zero order. You can see this by comparing experiments 1 and 4. After realizing that, you can then disregard all changes in concentration of [C] and only look at the first two columns to find the order of the other reactants.
