Items in Facebook product sets gone and content ID missing

Hi there,

– I’ve created a Facebook feed and get an event error on my “ad to cart” event because of missing Content ID’s. I see in my Facebook catalog that all Woocommerce simple products are fine but parent products don’t have a content ID. Anyway to solve this?

– I’ve created multiple product sets (by product type) corresponding to the product categories in my Woocommerce store. Everything was fine but just noticed that all the items within the product sets are gone. If I look at “all products” they’re displayed, but in the the sets nothing is there, although Facebook registers how many items are in the product set.

Any idea why this happens?
This is my feed url: https://bcork.dk/wp-content/uploads/woo-feed/facebook/xml/facebook.xml

Thanks
