Links requiring two presses on Safari and Chrome Mobile -- Debut Theme

Hi all,

I have just created a website for my client using the Debut theme as a base, this is my first website I have created on the shopify platform, but I have a passable working knowledge of Javascript and Liquid.

I have noticed that only on Safari mobile that most links require two presses when the page first loads up, if i go back a page the links work first time. I have waited until the pages are completely loaded, and this issue still is there. It happens on Safari and Chrome but not on Firefox.

I have not edited any of the Javascript files on the site, I have only added sections and modified the CSS for my clients needs.

The site is www.chalkevalleysoaps.co.uk.

Many thanks

ALex
