After upgrading to 4.4 BP Brush Details missing

For some reason i no longer have details populating in my details tab for BP Brushes. ANyone know where to look or reactivate this?

Nevermind. For those beginners like myself, if this happens I fixed it this way:

  1. Select Window
  2. Select Details
  3. Select one of the Details 1,2,3,4 Then retab.
