Delete Bookmarks from Launchpad?

Hi, how are you? I'm posting this question cause I haven't found it anywhere else. I installed Chrome and it installed on my Launchpad three bookmarks of sites and I cannot delete them. Don't know why those are there, I have a lot more bookmarks and only three appear and I even deleted the bookmarks but the icons in the Launchpad won't go. Any ideas? Anybody with the same problem? Thanks in advance!
