No Results

Hi, I downloaded this plugin and have been trying to make it work for almost 2 days now. I watched the videos, I read the step by step doc, but whenever I choose an item on the widget, I get nothing. It goes back to the home page with absolutely no results. I don′t know if it has anything to do with another plugin I use. In that case, I use Elementor, Content Egg, EWWW Image Optimizer, and Yoast SEO.
What I am testing right now is a checkbox filter with the name Marvel Heroes. I have about 20 posts, each of these posts is a Marvel Hero, so I want to put all of them in the filter. But I am testing it with 5. I go to the plugin, put the name of the 5 heroes, one in each of the Item Name, in a Filter Section called Marvel Heroes. Then, I go to each post, go to edit post, and choose, for example, the Ant Man post, I check the Ant Man box, and so on. On the widget, I choose the category (Marvel Heroes), click on Hide Taxonomies, because I just want the Meta Data, scroll down and save. When I go to any page and check the Ant Man box on the widget area, it loads and goes to the home page with no results at all. It′s like there is nothing on the post. Also, theses pages were made using Elementor. Almost all of my pages and posts were built using Elementor.
