Projects breadcrumb link points back to Blog (site error?)

Hello again, I have set the breadcrumb trail to show on my website. When I am viewing a project, the breadcrumb appears as Home > Project > (project name). When I click on "Project" to return to the Portfolio page, it takes me to the Blog page instead! Is this a bug in the site or something I can fix in my settings? My site is www.leikeladesign.com Thank you, Leikela
