Hello,
Ok- this is odd- but we can continue to rule out some things:
-Have you tested with only WooCommerce, WC Vendors and WC Vendors Pro active? (all other plugins deactivated)
-Have you tested using the Storefront theme?
-Do you have this checked: wp admin > woocommerce > wc vendors > general: Give vendors any shipping collected per-product
-(wp admin > woocommerce > settings> shipping > vendor shipping) DO you have this checked as a standalone method?
– Try resetting the vendor & pending vendor roles, in case the permissions are being ignored for some reason: wp admin > woocommerce > system status > tools: reset WC Vendors Roles
If these troubleshooting steps do not isolate the issue, please pass along an admin login & password in a private reply, and I will take a look.
