[Zerif] Testimonials is disappeared

hello Zerif team,

Thank you for your great team.

I am using Zerif on my localhost, I got a problem with testimonials. It is disappeared when I active the plugin https://codecanyon.net/item/my-team-showcase-wordpress-plugin/7371735. If I deactivate this plugin, the testimonials appear again.

Could you please help me to solve this problem.

Thanks
