This plugin saves the time for theme developers/designers writing codes.
When you are using ACF, tab fields for ACF is displayed. The default tab is hidden. 
If you need the default tab while you are using ACF, please add this code below into your theme’s functions.php

function register_default_tab() { 
 register_cfs_tabs(‘Defaulttab’);
