Org levels missing from the OTBI report for the inactive tree

We recently did our restructures and created a new version of the tree. The old version end on 2-Jul and the new version starts from the 3-Jul.

Now the Org tree has levels from Level 1 and goes upto level 7.

We have a OTBI report (using the Assignment Events subject area) that pulls the person name and other details and also the Org levels. Now when we run the report, it creates 2 rows per assignment. One for the current assignment details and the other row for the Pre-3-Jul assignment details. But what it does is, the org levels it only pulls the current and leaves it blank for the Pre 3-jul records due to the fact that those levels are not active.
