Menu issue on iPhone

Hi
I use your theme both for my day job and a small business I run so I have a few sites running it. One thing I noticed is the main menu doesn’t appear if you have sub-menus under it. You can select the submenus and they open fine, however, the main menu won’t appear unless you keep your finger on it and wait till a new window opens that gives you an option to open in a new window. When you select this option is work however it opens in a new window, which is clunky.

Have I missed a setting or something?
