Beaver Builder conflicts with max megas menu in Wordpress

New to Beaver Builder. Installed Max Mega Menu widget. Max Mega Menu changes will not display . When I de-activate Beaver Builder is does display, but loses all the site changes made with Beaver Builder as well as ( I think) the Astra theme. When I activate Beaver Builder all is well, excepting, again, I cannot again use Max Mega Menu, Thanks in advance for any suggestions.
