Product that belongs in multiple categories jumping from one to another

[chuender]

I have a product that is linked to multiple categories, lets say category 1 and category 2. When I drill down to category 1 and click on the product the category switches to category 2. Thought this might not be a huge deal, but when users click on the Listing button on product info page of product 1 they are taken to category 2, which is confusing.

How can this be resolved?

Example:
http://www.ijenco.com/ph-portable-c-177_208.html

Notice you are in category pH > Portable. This is evident the side nav and the top category tab. Click on the first product. Although the product info page does not have a side nav, you can see the category has been changed to ORP in the top nav.

What happens if you turn off your SEO/SEFU module?

Great call. I enabled "Add cPath to product URLs?" in SEO URL and it resolved the problem.

Thank you for your help.
