Basic Ledger

[D&J Soyring]

Anyone,
 
I am wonder if anyone you can help me.  My problem is that I generally use the single line general ledger register to enter my data and to keep a running balance.   Some how I did something to change this to the double entry registry without any balance shown.
 
Could you please tell me how to get back to the single line register.  I am using the latest version 2.6.3 of GnuCash since I have tried many other things as well.   Such as under "edit" preferences checking the basic ledger with no change.  Also under "view" the three "Basic Ledger", "Auto-split Ledger" and "Transaction journal" are ghosted out and I cannot change them.  The "Transaction journal" is checked but I cannot get them to be active.  Also the "Double line" is unchecked.

 
Please if you can tell me how to get back to the single line register.
 
Thank you in advance for your help,
Don Soy
