Hi there, hmmmm I’ve only started with the most recent version of the theme which is 5.3 I believe, so I’m not sure what the setup was for previous editions.

I would say the best bet to resolve would be to download the latest version from your ThemeForest account and install that to replace your existing version of the theme. Also disable all other third party plugins (those not required by the theme) to see if they are conflicting with any of the WordPress admin area.
