Show / Hide Interaction acting strange on iPhone

Hey folks, is anyone else having minor bugs when using an iPhone to view your designs on a live site? Specifically interactions.

Here is my problem: I have a list of links all within in a section on my landing page. I have separated this list into two div sections so that I can expand (show and hide) and minimize this list. It acts as it should when expanding out, however when minimizing, the screen jumps to the Contact section on the landing page below. Is this a coding bug? It only seems to occur on iOS.


Here is my public share link: LINK
