Having trouble excluding “static” home page from nav

I set a “static” home page and now cant seem to exclude the home page from the nav bar.

I have tried using the exclude and include template_tags to no avail.

It seems to be coded into another php file but I cant find where.

I have scoured the forums and found people with similar problems but cant find a fix for my particular theme: Sharpfolio.

Im trying to set up my first wordpress site and am pretty new at this any help would be hugely appreciated. The site as I have it now can be seen at number307

Thanks
