I'm not sure but maybe it's a bug:

In my site about videogames the games have an asociated term for its developer company and I've added this term as a filter. It works, but for any reason there are terms not shown in the filter. For example:

http://www.pixelgordo.com/categoria/genero/peleas-vs

As you can see in the view, there are a lot of games developed by SNK. But if you see at the bottom of the page where the refine filters are located this company is not shown, only

  • Capcom
  • Rare
  • Acclaim Studios Salt Lake City

appears...

Is it a bug?

Kind regards.
