Steps to reproduce:
Search 5! in Kagi.
Calculator should open. Instead it redirects to Fiverr.
On DuckDuckGo this works correctly. To use the Fiverr !bang you have to type !5 with exclamation mark in the beginning. I think they made an exception for !bang because typing "a!" (Or "!a") opens amazon website in duckduckgo.
