Hi sanghojeon

The title is automatically added via "add_theme_support( 'title-tag' );" so here is you can remove the title:

Can you please add the following code in functions.php (end of file):

// Remove title tag
function custom_remove_title_tag() {
    remove_theme_support( 'title-tag' );
}
add_action( 'after_setup_theme', 'custom_remove_title_tag', 10000 );

Please read the following article to learn How to Add Custom Code to function.php

Thank you.

Hi sanghojen

I have removed the code i gave you previously 

// Remove title tag
function custom_remove_title_tag() {
    remove_theme_support( 'title-tag' );
}
add_action( 'after_setup_theme', 'custom_remove_title_tag', 10000 );

Now and you have to install additional Plugin to Help you with it : Yoast SEO, watch any tutorial to see how to use it. 

Proxima font is fine is working, you can delete the other one.

Thank you.

Hi sanghojeon

Glad to hear that

P.S: If you like our theme, it would help us a lot if you could give us a five-star rating on Themeforest from your Downloads tab.  A huge thank you from Laborator in advance and have a great week!

Will set this ticket as solved from here.

Thank you.
