Error in Safari delete specific words in the address bar

I had a weird problem with the safari address bar. Certain words would be deleted when I try to write them. 

The error occurred in both Safari and Safari Technology Preview - and with all Apps on my Mac running and not running. I also tried to deactivate all my safari plugins.

The problem was very hard to find because most of the deleted words were deleted because of a specific word within a sentence it would not occur regularly and most of the time, because of my fast typing, it felt random. But I did find a word that would be deleted every time. That word for me was "Mie". Because of this I could replicate the error and fix the problem.

You can se the problem here: 

As you can see the problem occurred many times but other words works fine.

I found the fix

I had to deactive "preload top hit in the background" in safari settings - search. In danish: Safari indstillinger - under søg: "forudindlæs tophit i baggrunden"
