Search Fitler Custom Options

I have the Advanced search installed. Without anything added in the Settings> Advance Search Options, the widgets work how I want with a FIND and NEAR fields and search box. On one page I want to add the ability to refine the search options, so I add the extra options in the Settings> Advance Search Options and add default as click and the button to display on click. All good, but the CUSTOM SEARCH button gets added to every search widget on the site. I tried added CSS `.showFilters {
display: none !important;
}`
to block it but it blocks on the page I want the options on and then I tried to hard code the search onto the page with custom styling and new CSS, but that screwed up the search results.

I’ve tried on two themes, the basic GDF Modern and Avada. Same on both.

Also, there seems to be no way to add a simple single field search box on pages, only the advanced box.
