UNABLE TO CHANGE HEADER IMAGE

Hello,

You can have different header pictures by using this option :

You need to go to WP Admin -> Pages -> Your Page -> Set Featured Image (right side of the interface)

Please, see : https://cristian-extendstudio.tinytake.com/tt/NTE5MDkzNF8xNjI0NDAzMA

You also need to activate the option from Customizer -> Hero -> Inner Pages Hero -> Background Type -> Image -> Options -> Show page featured image when available.

In this way, you will have different header images for each inner page.
