3221297 - Page filter in combination with "not assigned" in a hierarchy not working as expected

Create a table and a page filter for it in SAC.  When selecting a value by Page filter, additionally Not Assigned value is shown as well. 

For example,  page filter is created with below values, if select Country 1,  Country 1 and Not Assigned node values are all displayed. However, it is expected only Country 1 value to be displayed.

  All

>Country 1

>Country 2

>Country 3

>Not Assigned node

Now select Country 1 for page filter, it displays as below:

>Country 1

>Not Assigned node

The expectation is as below, only Country 1 value is displayed:
