Currently you are using outdated versions of WooCommerce, WC Vendors and WC Vendors Pro. As well as WordPress , your theme Pasar, your payment gateway.. pretty much everything is in need of updating. Please update. Backup your site before you update— this is important, since much has changed in all of our plugins- especially WooCommerce. With you using these older versions it will be difficult to assist, since so much has changed.
I also see that you are using shipping zones AND Vendor Shipping. I order for Vendors to be able to set their rates, they need to use Vendor Shipping.
Also this should be fixed:
