ERROR: Menu nav has different font weights, cannot fathom why…

Hi,

I have a custom responsive menu in my site which currently works almost fine but I have a few issues.

1. The font changes depending on the page. I cannot find where in my code this is happening – it makes sense to me that it would occur when the page in question is referenced but I can’t see how. The font on the ‘About Us’ pages menu is correct – whereas the rest is not.

2. The drop down menus stretch a ul item, I’m wondering if anyone knows a way of the drop menu inserting into the menu as opposed to stretching the object below and fitting in there.

The first issue is more pressing, please any help would be really appreciated.
