Hi @bigbankclub
The p tag is automatically created when you inserted a new line. If you want to remove it on the front end, you can try the following code:
function my_acf_add_local_field_groups() {
remove_filter('acf_the_content', 'wpautop' );
}
add_action('acf/init', 'my_acf_add_local_field_groups');
I hope this helps.
