This is happening in your Varnish or whatever reverse proxy you have set up to do caching. I assume that it should be enough to configure the system not to cache responses to POST requests. (Since the text seems to appear after you click "Apply", i.e. probably a POST form action.)
Please reopen if you believe that this is not the issue.
