Owl City Fireflies Glitch

Near the end of the third chorus in Fireflies by Owl City, there seems to be a glitch when the special tappers start to appear. It starts off with the 3 special tappers that you have to tap at the same time but the ones on the far right and on the far left are needed to be held to gain points. The screenshot below shows what i mean. The ones inside the red ring are hold taps. I just wanted to show this so newer taps won't have the same glitch again. By the way I know the score is crap because i rushed it. Normally i would get a top 100 score
