Background For Header on subpages

Hi Noda,
It was working just fine now I only get the image on one of the subpages pages instead all of the subpages.

I have the image on this page

Beneficent Breath | Breathwork Coaching

I don’t have the image on any of these pages. What did I do!

Beneficent Horse | Equine Gestalt Coaching Method®

Beneficent Nature | Eco Coaching

Beneficent Bird | Falconry Coaching

this is the CSS that we are using

.page-id-4550 #header-inner.nav-type-2 #header-inner-bg {
background-image: url(http://beneficentforces.com/wp-content/uploads/2018/06/Feather2.png);
background-size: cover;
background-repeat: no-repeat;
background-position: center center;
}
#undefined-sticky-wrapper {

}
