Issue Summary

This is reproducible on Data Center: (yes) 

Currently, in the Forecast page, using the "Apply Backlog Rank" function is not working as described in the Run a forecast article. Instead the rank from the backlog is not being applied, generating divergent screen ranking

The portfolio level rank resets epics to the same order as the epic backlog for the PI.

Steps to Reproduce

1. Login to JA.
2. Select a Program and go to Forecast in the left panel.
3. In the top Selection, select "Program" and "Epic (Portfolio Epic)"
4. Click on "Apply Backlog Rank", and select the Program name under "Portfolio and Program Increment Level Rank"
5. Now duplicate the tab and go to Backlog in the left panel.
6. The Epics shown in both reports should be in the same order

Expected Results

Both the reports should have features or Epics as per selection, in the same order.

Actual Results

Forecast and Backlog show different orders when Apply Backlog Rank is used.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
