Reproduction Steps:

0.) Use a vanilla bundle with the latest fix pack.

1.) Create a new site, and add 7 pages, the structure should 4 level parent and child pages. Please find below illustration:

-page1
--page11
---page111
----page1111
---page112
--page12
-page2

2.) Go to page111 and add a Navigation Menu select Configuration, in the popup select:

• Root Page --> Relative Parent Up By

• Root Page Level --> 2

• save the configuration and close the popup.

Expected: the portlet shows page11 and page12.
Result: You will see page111 and page112.

Note: It seems that the level goes in the opposite direction. Also, LPS-82709 handles a similar issue, but only solves the problem on Relative Level 0.

edited: set root page level to 2, since based on the requirements in LPS-82709, level + 2 should be the parent level.
