Breadcrumb showing incorrect category

Here's my problem, I have one product that is in two categories.



e.g.



Product 1 is in Category 1 and Category 2



So I want the Breadcrumb to display Category 1, but it will always display Category 2, even though Category 1 is selected. If I remove Category 2 then only Category 1 will show, but upon adding Category 2, it will always show the category regardless of what has been selected.



Any ideas?
