I am sorry to hear of your mishap, but I regret that there isn’t any undo capability for Quick or Bulk Edit operations in MLA.
I am marking this topic resolved simply because the question has been answered. I hope you can recover or repair the information you need without too much pain.
Fortunately, I had a recent back-up of the database. Ended up importing that database. Just another good example of having back-ups.
I am happy to hear you had a usable backup. I have learned that lesson the hard way several times over the years, and I now back up more often than not.
