In a main subject there are amounts for sales total and a purchase total (“Kale kostprijs”). The purchase amount is a total of a detail subject. When he result (sales total -/- purchase total) is positive (or zero), the result amount is shown in green, otherwise in red.

After adding rows in the detail subject, the total of the details (purchase) is updated to 21.00, the result to -1.24 but the conditional layout for result is still showing green. Because it is a negative result, this should have been red.
 

How can I update the color of the column result (conditional layout) at the same time as the “Kale kostprijs” and “Resultaat”?

The extended property "RefreshOnTabSwitch” is already set to “Yes”.
