Are you adding the description settings in the metabox or globally? Please note the following the order we follow to generate meta descriptions for WooCommerce product:
1. Content from SEO Description field
If that is missing, then:
2. WooCommerce Excerpt or Product Short Description
If that is missing, then:
3. Template From General Settings in WordPress Dashboard > Rank Math > Titles & Meta > Products
If that is missing, then:
4. Auto-generated Content from the product page
