Pattern does not match

I use list items from a file. See the following screenshot (I hope this works …):

On top you see the first five lines of the file containing the list items “Absender” (sender). The last three lines show different patterns of the same sender (Campe & Ohff). On the right of the screenshot you can see that this pattern is not matched—though it’s clearly displayed … I don’t get it.
