So what? This is not a problem and it needs no fixing. There are many cases where resources could be re-used but they were not. There is nothing right or wrong about it. Using different resources for different pages makes it flexible to have different labels on different pages. In this case if I were doing it today I would probably use the same one, but its not important, this work is done, it works and it needs nothing.
Better to spend my effort on important things than to constantly polish unimportant ones.
I recommend just translate them both the same and move on with life.
