Problem filtering a page's collection by taxonomy using the url /tag:nameofthetag

I don’t manage to get a filtering of my page’s collections “by taxonomy when one has been set in the URL (e.g. /archive/category:news)” (cf documentation: Page Collections | Grav Documentation )
I have also read the part about taxonomy ( Taxonomy | Grav Documentation ) and enabled it, I made the tags visible on the page (with a url that should filter the collection — ex: /tag:nameofthetag ) but when I click on them it doesn’t filter at all…
Any idea why?
