Provenance no longer a filter variable?

Until very recently, one feature I liked was the ability to filter listings in the "for sale" forums by provenance. Being based in the EU, I would simply click on the EU flag and get only posts from sellers based on my side of the pond. But a few days ago, I noticed that this possibility was gone, and the filter menu no longer offers that possibility to narrow a search.

Not a big deal, but I just wanted to express that I miss that simple and quick feature. Is there any plan to bring it back eventually?
