1. Download attached folder containing camera FBX files
2. Create a new blank project
3. Create a new Level Sequence
4. Open Level Sequence
5. Go to General Options < Import
6. Import a camera from the folder that was downloaded(Step 1)
7. For Import settings leave Force Front XAxis unchecked and Create Cameras Checked
8. Import
9. Note the Current Focal Length
10. Repeat the import process with a second camera
11. Note the Current Focal Length of both cameras has changed to match the newly imported camera
12. Repeat the import process with a third camera
13. Note that all cameras Current Focal Length has changed to match the Current Focal Length of the newest camera

Expected: Each imported camera keeps its own Current Focal Length and is not changed to match any imported camera
Results: Current Focal Length changes to match an imported camera so all imported cameras match whichever camera was imported last
