Active Camera Not Working

Frustrated with this scene, doesn’t render using the active camera. Looks like a bug. I want it to render using the orthographic camera, ‘Camera.001’, the 3D viewport shows it as the active camera, but when i render the scene, it uses ‘Camera’ to render it. Have attached the file:ActiveCameraNotWorking.blend (116 KB)
Please have a look at it, if you can spot anything i’m doing wrong, would really help me.

Select your Camera.001, and type Ctrl-0 to make it active.
Press the “Lock” button in the 3D window, it must be shaded to see by this camera.

Thank you so much!!! really stupid of me… must have accidentally turned the lock off. :o
