First voice and second voice have the same pitch but different lengths?
I saw this in this music ( https://musescore.com/user/1784886/scores/3188581 ). The green note below is a second voice, right? And the first voice has a note with the same pitch. Aren't two voices supposed to be played in one piano by the same person? Then, when you are actually playing it on the piano, how are you supposed to play the two at the same time? The B3 in the first voice is a dummy?
