Profile page change in source system balance behavior?

Summary

On the Profile page in ARCS it seems the way that profiles are displaying source system balances has changed in recent months.

Hi all,

Fairly new to the ARCS product and we are a making a lot of mapping changes to either group or ungroup data into more/less detailed reconciliations.  In the last month or two we think we are seeing a change in how the source system balance is displayed on the profile page when updating mapping.

	Account ID	Source System Bal
Old mapping	All_BU-1234567-AllTC-ALLBC	1,000,000
New mapping	0100-1234567-AllTC-ALLBC	500,000
	0200-1234567-AllTC-ALLBC	500,000

Prior to the March update when we made this type of a mapping change the amount on the profile page for the old mapping row would become blank and the new profile rows would show the split out balances of 500,000 each.  Now we are seeing that the old balance are not going away, they are not being turned into a blank even though we are getting the details on the two new profile rows as intended.
