Confusing message on Google Analytics

I'm not sophisticated about Google Analytics, but I use it to track basic performance parameters for my website.  I've created custom filters, to exclude data from referrers which have no genuine relevance to my business.  Now I see a message in Analytics which says I should delete unusued filters, because they are "not applied to any views".  This is confusing, because the filters are applied to my principal view, and they are effectively avoiding distortion of the data which otherwise results from traffic originated by spam bots, etc.  Why am I receiving a message which says the filters are not applied to any view?

This is a known bug. If you don't have duplicate filters, and all of your filters are being used, you can safely ignore the message.

Check QUANTITY of filters and MATCH used filters.
Check for DUPLICATE filters.

Thank you both for commenting.  I've attached screen shots of the message, the main Administration window, and a partial list of filters applied to the view.  There are no duplicate filters.Analytics MessageAdministration Main WindowPartial list of filters

Do you have any alternate views or properties which may have unused  filters?
ddantesAuthor Commented:
Not in that account.

Since you thoroughly refuted the warning with diligence,  I recommend ignoring the warning  (known bug). I would go the extra yard and report this known issue to Google to unite with the motivational consensus to pressure them to solve the error quicker.
