navigation is hidden

Hello, everyone! 
I have the following problem: 
In the editor, the navigation is displayed correctly, but when viewing the site itself, the right side of the navigation is hidden. 
If you go to the internal page of the site, the navigation works properly.

What code have you used for the split navigation?

It's certainly there, but not remotely displaying correctly:

(from this site: https://www.squarestylist.com/blog/secondary-navigation)
this:

.header-actions .header-nav-item {
  padding-right:1.1vw !important; /**change as needed**/

}

.header-nav-list   {
  display:-webkit-box;
  display:-ms-flexbox;
  display:flex;
  -webkit-box-pack:end !important;
      -ms-flex-pack:end !important;
          justify-content: center!important;
  .header-nav-item {
     padding-right:1.1vw !important; 
   /**change as needed**/
  }
}

.header-actions--right {
  display:-webkit-box;
  display:-ms-flexbox;
  display:flex;
  -webkit-box-pack:justify;
      -ms-flex-pack:justify;
          justify-content:space-between !important;
}

.header-actions .header-nav-item {
  padding-right:1.5vw !important;
  //change as needed

}

.header-nav-list   {
  display:flex;
  justify-content:flex-start !important;
  .header-nav-item {
     padding-right:1.5vw !important;
    //change as needed
    
  }
}


.header-actions--right {
  display:flex;
  justify-content:space-between;
}


.header-nav-folder-content {
  opacity: 0;
  pointer-events: none;
  position: absolute;
  top: 2.5em;
  margin-left: 0em;
  padding: .0em .0em;
  text-align: left;
  box-sizing: border-box;
  width: 185px;
  z-index: 10;
  padding-top: 0.5vw;
}


.header-nav-item--folder:hover .header-nav-folder-content, .header-nav-item--folder .header-nav-folder-content.focus-within {
  opacity: 1;
  pointer-events: auto;
}

 .header-nav-item--folder:hover .header-nav-folder-content, .header-nav-item--folder .header-nav-folder-content.focus-within {
    opacity: 1;
    pointer-events: auto;
  
}

.header .header-nav-wrapper a {
  padding: 0;
}
.header-nav .header-nav-item--folder .header-nav-folder-content .header-nav-folder-item {
  line-height:1.9em;
}

I noticed a pattern that navigation is hidden only on these pages

That isn't a solution that I've tried before, and I'm not sure why it would be working on some pages and not others. Can you ask in the message board on the website?

@squarestylist Would you be able to help here?
