Issue with Shadows? Or Rendering Issue

So I have this weird issue with my Shadows, I think its my shadows at least. I had this issue a long time ago and I got rid of it by Setting my Engine Config file to default. However, after a few months of working on my game (and not changing any settings related to lighting or shadows) I have this issue again. This time I want to find the permanent solution. Anyone know whats going on?

Could really use some insight please, this is really putting a huge halt on my development process.
