Wrong German Translation in Book GUI "Schild" instead of "Signieren"

If i write a book, the left button should say "Signieren" but now says "Schild".
Thats a funny mistake. "to sign" can be "unterschreiben" or "signieren" in german. But deffenitely not Schild a "Schild" is indeed a sign. But its a sign placed on streets or walls xD

why did you change this annyway? seems to be a new trend to "fix" things that are not broken recently! Please change it back...
