Hello,
We checked the issue in more detail and found that problem is related to the compatibility of the multivendor plugin and Elementor page builder. We have contacted plugin author here https://wordpress.org/support/topic/compatibility-with-the-elementor-2/#new-topic-0
So, follow that request and wait until they provide any fix. We are not able to solve the issue from our side because that is a plugin bug.
Regards
