Monika,
Someone invented Ctrl/Cmd+Z for Undo some time ago (to unbloat anything bloated among other things), and sometimes something unexpected may grace us with its presence, so why not try? And note the first 5 words in the first sentence of the first post.
Makes just no sense at all.
Some might find such a (third) statement redundant, and a bit harsh.
Obviously, I may have a harder time with the German (and hesitant to rely too much on the English translation) than you.
