Enfold errors for PHP 7

Any idea why I get the following errors when running PHP Compatibility checker on Enfold?

4207 | ERROR | Function split() is deprecated since PHP 5.3 and removed since PHP 7.0; use preg_split instead
5637 | ERROR | Using ‘break’ outside of a loop or switch structure is invalid and will throw a fatal error since PHP 7.0

Running version 3.8.4 on WP 4.6.3 on WPEngine (hence not WP 4.7.2)
And will this adversely affect me moving to PHP 7?

Thanks
