Movable Directional Lights only cast shadows when camera is looking up

This is a really strange problem, but it seems like when Directional Lights are made movable they only cast shadows when the camera is looking a certain direction.

Here are some screenshots, one of looking straight ahead: http://i.imgur.com/XSPTidl.jpg and one of looking down at the floor: http://i.imgur.com/Or5yBhY.jpg

Does anyone know of a fix for this?

Thanks in advance!

Never mind, there was a little arrow under the Cascaded Shadow Maps panel which had some more options, changing Far Shadow Cascade to 4 fixed my problem.
