Sub Menu Errors

We have Beaver Builder Plugin Standard Version installed and for some reason the drop downs in the main menu are not working. Can someone please help me fix this?
The site can be seen at multipress.com
I noticed there is several errors pertaining to the menu:

www.googletagmanager.com/gtm.js?id=GTM-T7DJ7L6:1 Failed to load resource: net::ERR_BLOCKED_BY_CLIENT

jquery-migrate.min.js:2 JQMIGRATE: Migrate is installed, version 1.4.1

Your menu looks fine to me though I have never been to your site and you are combining all scripts and stripping asset versions so its highly likely you updated something and are seeing cached old js because of over optimization.

Also dd-menu.js is not part of any Beaver Builder product.
