Products Not showing in Category pages after csv import

I have tested uploading products with a couple different import plugins, but no matter what I use WooCommerce will not SHOW the products in their respective product pages as it should.

I have made sure all categories are entered correctly. I can view the product and all correct info in the product page in backend once uploaded. Even the categories are selected properly, as was indicated in the csv. But only after individually saving the product several times and refreshing the category page several times, and waiting at least an hour, will the product show up on the page.

This is seriously inconvenient. Anyone else having this problem, or know how to fix it??

Thanks.
