Slip Entry Preferences

SOLVED

Good morning - I upgraded to 2015 and find that the Slip Entry field has changed a bit in that a couple of fields have been added (reference and extra) below the task field.  Both are unnecessary for me and would like to remove them -- is this possible?  If so, how?  I have looked under the set-up/preferences tab but cannot figure it out. 

Also, I would like to have the date default to the date I just entered on the previous slip rather than go back to the current/today's date as I enter slips after-the-fact in batches from all partners by date (we do not use the timer).  Can this be changed as well?

Thank you
