When I am in the WP backend on the Facetwp settings page (or anywhere else), and I do FWP > clear cache from the top menu, the page redirects to options-general.php. Don't know if this has a reason but it is annoying when you want to reset some things, do a re-index and clear caches, and each time you have to navigate back to where you were.

Better would be to reload the current page, if possible.
