Did found out the following:
I entered 25 * 2 in the address bar of the browser.
Using Edge the url looks like this:
https://kagi.com/search?q=25+*+2&source=chrome.ob
In Vivaldi on Windows the URL looks like this:
https://kagi.com/search?q=25+*+2
If I enter the text 25 * 2 in the entry field of the kagi.com page, then it works ok in both browsers.
So Edge does handle the search text in the address bar differently. I don't know why.
The search engine url in Edge search settings for Kagi is exactly the same as used in Vivaldi:
https://kagi.com/search?q=%s
If I change the URL in Edge to https://kagi.com/search?q=25+*+2 (and thus removing the extra query parameter source) it also works ok in Edge.
So my conclusion is that Kagi cannot (correctly) handle the source parameter or is confused by it?
NB: Afaik the setting of Edge are standard, so I didn't change anything I can think of that could trigger the addition of the extra URL parameter.
