Everest Pro 3.3 theme. mobile width incorrect with many plugins

Using the Everest Pro 3.3 theme, with a cell phone in portrait mode, many plugins run off the right side of the screen: Some examples: tablepress Zedity (free and premium) pagebuilder If no plugin was used, the page displayed correctly. With so many plugins not working, the problem is clearly with the Everest Pro 3.3 theme. Any suggestions on how to get this bug fixed or work around? Thank you.
