Helix Ultimate SmartSearch Result generates "highlight" URL, which dont work

Hello,
we have on our page Smart Search in header activated. When i search for any word we will get a result. So the search itself works. We get a result like this, e.g. for a serach with "Maddin":

The URL of this page is: https://www.breisig.live/component/finder/search?q=Maddin&Itemid=304

Problem: The Search adds a "highlight" to the URL when i click on this result:

https://www.breisig.live/events/maddin24/highlight-WyJtYWRkaW4iXQ==

The correct url would be in this case simply:

https://www.breisig.live/events/maddin24/

How can we fix this?

Thank you!
