When new blogs are created, there is not a / between the base domain and the sub directory?

The title basically describes my question. I have everything setup correctly to my knowledge and the blogs are being created fine. However, when they are created they don't contain a forward slash in between the base domain and the sub-directory (see screenshot). I can go back in and change this manually and everything will work fine.

Also, it is not setting up the domain mapping. Once again I can do this manually, not sure if the issue is related.
