Instagram Product Tagging / Google Product Field Issue

Hello! Recently I’ve been dealing with a tagging issue for the past few days. All my products are populating in the Commerce Manager Facebook Catalog under Items, and when I create a post on Instagram and try to tag the item it is greyed out and shows the following message - Product cant be tagged - This product is unavailable, missing information, or doesn’t follow our commerce policies. I go back to the product on Shopify and usually the Google field is errored out and gives the following error - missing size, missing gender, missing age, etc. (this information is filled out though) So I go ahead and delete the Google Product Category information and save the product, then I input the same information and save it again. This then has the product show up in Instagram to tag in a post, but then it disappears again and shows the same error. I really am so confused how I should troubleshoot or resolve this very frustrating situation. If anyone has encountered this product tagging issue and google product category issue please help! I’m desperate.
