Will a website be affected in anyway by having different pages with the same button title?

Will a website be affected in anyway by having different pages with the same button title? These pages have different meta titles, keywords, etc but have the same button title for the sake of the navigation panel. For example, there are four pages with the button title '686' but the page meta's vary because they are classed under different categories - Men's 686 Jackets, Women's 686 Jackets, etc.
Just wondering if when the website is crawled, the search engine spiders will get confused and mark the site down for this reason. Any knowledge to be passed on this subject would be great.

Here the sitemap if you need to have a look - http://www.snowboarding-jackets.net/Sitemap.html

Thanks :)
