Grouped meshes appear to rotate when used in streaming levels

Grouped meshes appear to rotate when used in streaming levels. If the parent of the group has a rotation, it appears to pass this on to the rest of the group after the meshes are streamed in. As a note: please be sure to walk far enough away from the doors or the issue will not show. (see screen shot for example)

1. Download the project from the link provided
   [Link Removed]
2. Open the project
3. Play in Editor
4. Walk through the doors (they have no collision) (walk far enough to exit the streaming volume)
5. Walk back through the doors (they have no collision) (walk far enough to exit the streaming volume)
6. Repeat this 6-7 times

Result: The bookshelves will rotate (see screenshot attached for reference)
Expected: The meshes would retain their original rotation when switching between levels
