Trade site function "listed" does not work

For example, this search:
https://www.pathofexile.com/trade/search/Standard/8PZzr48UV

In Trade Filters, there is a setting called "Listed", which, in this case, is set to "up to 2 months ago".

That should exclude all items that were listed more than 2 months ago. It doesn't. It shows the same results, regardless of that setting.
