Why is my Twig Override not displaying any content, when the original Twig was barely different and worked just fine? I'm overriding a Twig template for the responsive_menu module, and encountering an issue with content not displaying. 

The original Twig is named responsive-menu-horizontal.html.twig and my replacement is named block--responsive-menu-horizontal-menu.html.twig. Please note that the name of the replacement was derived from my Inspect Element debugger's suggestions.

The two Twig pages are almost exactly the same, save for the names and the added classes for the ul and li pieces

When I use my override for the default Twig page, the nav completely disappears, and my debugger leaves me with this: 

&lt;!-- BEGIN OUTPUT from 'themes/indyres/templates/block/block--responsive-menu-horizontal-menu.html.twig' --&gt;
&lt;!-- END OUTPUT from 'themes/indyres/templates/block/block--responsive-menu-horizontal-menu.html.twig' --&gt;


I'm confounded as to how it'll read my overriding template and render nothing. Any help/explanation is greatly appreciated, this is the first Drupal project I've ever worked on, and though I managed to keep my head above water in creating the styles for the rest of the site, this piece has me really lost.
After a lot of frustration, and realizing that I could (in fact) manage to get Superfish to do what I had originally wanted, I just composer remove'd the module and that's where it'll stay. Thanks for the help everybody!
