SETSELECTIONFILTER not working correctly in 2015

I'm using build 38798.

Try importing these two pages and running page 91000:

OBJECT Page 91000 Main Page

    {
      { 1160180004;  ;ActionContainer;
                      ActionContainerType=ActionItems }
      { 1160180005;1 ;Action    ;
                      Name=Count Sub Page as Group;
                      OnAction=VAR
                                 integer@1160180000 : Record 2000000026;
                               BEGIN
                                 CurrPage.SubPageAsGroup.PAGE.GetRecords(integer);
                                 MESSAGE('Main Page Count: %1',integer.COUNT);
                               END;
                                }
      { 1160180009;1 ;Action    ;
                      Name=Count Sub Page as FactBox;

                               END;

What you will see are a main page and two sub pages which are actually the same page (91001). Only difference is that one is a sub page and the other is a fact box.

The sub page returns correct counts, also when using Ctrl+A or clicking in the left corner of the list. The fact box, however, does not.

The question is if anybody has found a workaround or know of a working build.
