Getting Attribute chgs from AC13.7 to AC13.1

I'm loading new activity attributes into ACIFATTR for existing activities that have an attribute already assigned for the matrix category being used in the ACIFATTR records.
I'm using today as the effective date.

Using AC510, the records are found, brought into the system and removed from ACIFATTR.

Run AC10 to view the activity, click on the Attributes button to access AC13.1 and I see that the attributes still contain the "old" values.

The "Eff Date" button now has an asterik next to it showing that records exist behind that button.
Click on the button, takes me to AC13.7, "Attribute Value Effective Date", where I see the new value that I loaded into ACIFATTR and that AC510 says it processed. Has today as the effective date.

I want THAT value to be the value that displays when the user pulls up form AC13.1.

What pulls that new value up to replace the "current" value?

Is there a processing step that I'm missing?

thanks for any input.
