A suggestion: don't hide the entire store component when you change one of the filters. You can see it flash with unstyled text "loading" before popping back into view. It's much less jarring if you keep the existing content rendered while waiting on the response and swapping it out after the request completes rather than going to a blank screen when you start the request.

My personal preference is more subtle loading indicators near the element that triggered the interaction (the filter inputs themselves in this case) but that's probably subjective. I think at the very least you should keep filter bar visible while it's loading so that the element you're interacting with doesn't disappear while you're using it and pop back into view.
