We are currently at TRIRIGA version 10.5.1/188.8.131.52
In the Navigation Pages if a particular Portal section with a report, has a result set of more than the property "Max Records Displayed", then the results are not shown, and the section just keeps loading as show in the attached pic.
This behavior is not the case if the results returned are within the limit set in the portal section. Also, when the section is maximized we can see all the results too.
It works in the case of a hierarchy query too
