Bookmarklets only produce bookmarks, no pdf or Webarchive

Suddenly, I don`t know why, my Bookmarklets in Safari only producing bookmarks instead pdfs oder webarchives.

Is this a known problem or what could be the reason?

I just tried the PDF and the Webarchive bookmarklets here and they worked as expected for me.

There are different bookmarklets for different document types. Perhaps the wrong one was clicked; or the bookmarklet names were incorrect?

After restarting my computer the newly installed bookmarklets work again.
