Unexpected result with constrained dashboard prompt fields

Hi,

I created a prompt using Opportunity object of Advanced Custom Objects Report Subjet area. I choose the Closed Date/Date field and a second custom field called Business Segment. Both prompt fields have the constrained flag set.

When I select a value for Business Segment I get a list of dates in the Date field which reflects only a subset of opportunities we have in CRMoD with the selected Business Segment value.

When I create the same prompt using subject area Opportunity everything works as expected.

Any ideas?
