Sorry, I did leave out some info. I am using subversion(not preforce) specifically. However when you attempt to connect to a subversion for source control via the Unreal Editor with a password that has spaces, you will encounter an error in which it will look within your engine’s binaries to attempt to find folders that are named as the separate sections of your password.
I have reset my password to a new password that no longer has spaces and I am able to use source control, but I do believe this to still be a bug.
