Header Navigation Menu not showing on one page

Hi everyone,

I am creating a website for a client using the AIRI theme (they have asked me to keep it unpublished just yet) and all is well except for one page (SERVICES) which is not displaying the header/navigation menu.

I am normally fine fixing these issues…but I’m stuck.

I think I have done something accidentally (either in visual composer or elementor free version). My global css settings are

.masthead-fixed .site-main {
margin-top: auto !important;
}

.masthead-fixed .site-header {
position: static !important;
}

.is-sticky .site-header .custom-logo-link img {
max-width: 255px ;
max-height: 157px;
}

.content-area {
padding-top: 250px;
}

Any help would be appreciated.
