Why don't previously entered Worker Contacts appear?

Worker contacts previously entered do not appear when I press Enter -- after entering my Worker ID and Contact Date. After entering Today's Date and Worker ID, I pressed Enter but the contacts I entered earlier do not appear. Why not?

CASEY
To retrieve contacts previously entered, press the F6=ContDate key -- after you key Worker ID and Contact Date and press Enter. We will study changing the program to automatically "press the F6 key" when you press Enter. 

Problem
When working on daysheets: A worker pulls up their day sheets and types in their name and today’s date and hits enter to be able to enter day sheet information. Once the worker enters information on today and updates and exits and then comes back into today’s day sheet later in the day and puts in their name and date and hits enter, earlier day sheet information does not appear until you press F9 or F10 for previous or next day and then return to today's date. 

This is confusing and appears to workers that the day sheet information they entered earlier isn't there and they enter it again only to later discover the information has been entered twice. Will you please correct this?

Once a worker enters their name and date they would like to see or work on and presses enter that information should appear. Instead we are having to fool the system by going to the next/previous day and then return to today in order for the information to appear. I've copied two screens below. The first is after I entered day sheet information and updated and exited and then came back in. As you can see the name, date and SS# are showing but not the information. The second item is after I pressed F9 for a previous day and then returned to today, the day sheet information appears.
