opencart. Mega Filter intercepts from REQUEST_URI #anchor?

Question

opencart

Shop on opencart. I made an anchor so that on click go to the element located below on the page. When you click on a link that contains #anchor_id, its value is transferred to the address bar, where the mega_filter search script automatically fires.
my_site.ru/#id -> my_site.ru/index.php?route=module/mega_filter/results
If you write my_site.ru/#id in the address bar, the filter also works and sends -> my_site.ru/index.php? route=module/mega_filter/results
How to make the filter not intercept the value from the address bar, or at least not touch the anchors?
