CB not working on Product pages when CBT is active

I have noticed this issue throughout some of the issues. However, I am unable to figure out what is going on / what I need to do to resolve it.

I am using 6.x.1.5. When creating a custom breadcrumb for a product type node. The modified breadcrumbs will not appear till I disable the custom breadcrumbs taxonomy module. I don't think this is a proper fix for the issue so I was hoping to have some simple direction.

Thanks
