The `default list filter` category setting, added following this topic: [In a top category page, show only its own topics below subcategories - #29 by sam](https://meta.discourse.org/t/in-a-top-category-page-show-only-its-own-topics-below-subcategories/39527/29), causes a nondeterminist behavior as far as I understand. It seems that setting it to “no subcategories” redirects the base category URL to the `/none` category URL. But sometimes this page displays the “_subcategory_” filter, sometimes it does not. Especially, the first time a category is clicked, this filter isn’t displayed. Hence, subcategories are nowhere to be found, completely invisible. Then, if I refresh the page, the filter reappears. It is plausible that the filter doesn’t cause the issue but rather just reveals it, because before this filter, the only way to access `/none` was to open the subcategory filter so it was already displayed and we never knew that sometimes it wouldn’t be displayed. If that makes sense. # Steps to reproduce - In a category, set the `default list filter` category setting to “no subcategories” and save - Access said category through any regular means, e.g. link in the menu - Subcategory filter isn’t displayed - Refresh, it is now displayed --- _[View the full topic](https://meta.discourse.org/t/subcategory-filter-disappears-on-none/386648)._
