How to remove characters in url after sign on Bitrix?

Question

PHP

I connected a smart filter to the CNC site, redid the links, everything works, but there is one BUT.
When I simply follow the link, a page with a format filter opens: http://your-site/projects/filter/room-is-jilie/apply/ , but if I apply the same or any other filter on the page, I get a link format http://your-site/projects/filter/room-is-jilie/appl... - how and where in this case it is possible to fix the formation of the link and clear everything after the "?" sign.
