Marketpress Categories still not working

Fullwidth theme

ADD NEW PRODUCT> Select the category. Not all categories are registering.

When you view the product it shows that the category is selected but when you click on the "category tag" that is displayed with the product(Screenshot1.) It directs you to the correct search page and that product is NOT there (Screenshot2.)

Thus, the product will NOT be in its designated category ... I've done everything...re named category slugs, deleted and added them again in all shops, cleared cookies and cache, re-freshed shops and categories... I am at a loss. I am not sure how to fix this issue.

I've been inquiring assistance about this for a few days and am on a deadline. Please advise with some follow through. I'm at a total loss on how to fix this? I've attempted everything that I know how to do to solve the issue. :disappointed:
