How do I reverse Title and Menus and set menus to RTL

I need to reverse the positions of the Title Header and the Menu Items. Title to right corner and menus to left corner.

Also, Menu items are displayed wrongly from LTR, even when settings WordPress to RTL language from admin panel.

So instead of seeing
Homepage | Who we are | Contact us

We see it as if it were
contact us | Who we are | Homepage

while Homepage is the closest to the center of the page which is odd to be in this order.

I kept looking through the code but couldn’t understand PHP :/
I’d appreciate an advise of what is controlling these elements so I can reverse it.

I looked in
rtl.css
Index.php
header.php

I see what I need to change is in header.php. But can see anything controlling whether to set it to left of right anywhere.
