We upgraded to Magento 2.4.1 and need to update Webkul Multi Vendor package. Thanks in advance for your attention.
I have checked the screenshot link you have shared and it looks like the extension is not compatible with the version you have upgraded.
Check compatibility with both the Magento version and the PHP version as well.
Raised the ticket on the Extension providers portal, they will help you to resolve this issue.
Hope it helps !
The price display settings determine if product and shipping prices include or exclude tax, or show two versions of the price; one with, and the other without tax.
