Hi!
1. You can set it here: https://i.imgur.com/tyrDsSe.png
Enter “unset” to the field, and the scrollbar will disappear 🙂
2. That I’m not sure. If this is on the results page, then it is outside of the scope of the plugin, as it is controlled by the theme. If you can share a URL to this, then I can tell for sure.
3. Well, it is the purpose of the filter. You might want to check and experiment with different checkbox logigs here: https://i.imgur.com/ScpExZx.png
Also make sure that this option is enabled, so if all checkboxes are unchecked, then the filter is ignored: https://i.imgur.com/lbVDK5a.png
