Prefix added to the title when accessing page with filter parameter in the URL

Hello there, BeRocket community !

I’ve encountered a weird behavior from the Ajax Product Filter plug-in, it took some time to notice :

When accessing an archive page (a brand archive here) with an active filter (in the URL), a prefix “Brand” is added to the title of the page. It does it also with archive pages of any attribute (with the Collection attribute as shown in the attached link). It doesn’t happen when it’s an archive from a product category.

When accessing the Brand archive page with no filter in the URL, everything behaves as expected, it’s only when accessing a page with a filter in the URL, like “?filters=matiere[1929]” that the prefix “Brand” appears in before the title.

I’ve checked all settings and I don’t think it’s a normal behavior. One solution I’ve thaught of is to disable “Refresh URL when filtering”, for now I like the possibility of sharing already filtered URL, it’s pretty convenient.

Open to all suggestions !
