Hi, Using only one page builder at once is necessary. Using both can make a lot of troubles with the HTML code of the page.
Also, if you want to use the WPBakery(VC), then you will not be able to edit our pre-built websites. They can be edited only with the Muffin Builder.
To select which page editor is primary, then please go to the Theme Options > Global > General Switch the "Content | Display Order" to WP Editor - Muffin Builder http://prntscr.com/mppu0r
