Yes, it does appear on every other page except homepage. The gap is caused by page-title section.
I see you’ve removed all the content from it, but not the page-title container.
To do that, remove the <div id="page-title" class="page-tit-7"> and its contents from every sub-page.
The second option would be to add the following code to style.css:
#page-title {
display: none !important;
}I prefer removing the unnecessary HTML code.
