It is not a bug, it is an improvement.  
 
Way back when (standard DBA) the Voucher description is what was saved as the description in the GL Transaction file.  Users asked for the ability to edit the line by line description so we enabled that capability but if you didn't edit it, the transaction line was saved with what was displayed on the screen, which happened to be the GL Account description.  If you wanted the header description to repeat for each line, you have to retype it.
 
Now, the GL Description is shown long enough to confirm that you have the correct account but saving the GL Transaction with a description equal to the GL Account description is pretty worthless, you already know what account it is when looking at a Trial Balance.  So you can edit the line by line description but if you do not change it, then it will be replaced by the Voucher Description from the header which is what will be saved in the GL Transaction records.

I HAVE THE 3-26 UPDATE - BUT I CANNOT GET THIS TO WORK - WHAT WE TYPE IN IN THE DESCRIPTION UP ABOVE DOES NOT PULL IN DOWN BELOW WHEN IT IS DISTRIBUTED - AND THEN WE ARE JUST GETTING A REPEAT OF THE ACCOUNT NAME IN THE GL UNLESS WE RETYPE THE DESCRIPTION AGAIN ???

No, there is no default setting.  When you first enter the GL Account, the Account description will pull in.  Wait until you advance the cursor to the Amount field and you should see the other description from the voucher header pull in unless you have edited the GL Account description.
