If the bill amount does not automatically compute after using the Global Edit feature you may need to edit the fees manually.  If you were in Bill Preparation you should have the Record Number available to you. Open up Fee Entry, and now click the magnified glass icon next to Record.  Enter your Record Number that is in question.

Now that the fee is displayed, sometimes you can tab through the windows and it will adjust.  If that does not work change the Timekeeper to a different Timekeeper and then change it back to the original Timekeeper.  The bill amount should now be there.
