Why does the custom label have 0 products

I am trying to create a custom label in order to filter out some products to advertize on google. But every time I try to create the custom label it says no products found. What am I doing wrong? My campaign on google ads is a standard shopping campaign. The products are approved and visible on google.

That means the data feed solution you are using, is not submitting the values you added.

I am guessing you are using the google and youtube app, if yes, ask for support here: https://support.google.com/merchants/contact/shopify_3p_support_app

You can also add the custom labels directly in Google Merchant Center, here are all the ways you can edit products in GMC:

Thanks for your help. I realized the products were not active in Shopify and the Google and youtube app! The issue is solved now
