I'm not aware that the delete content is broken in NBS v2, I know some people have had some trouble, but I've not been able to recreate the problem (Must say I've not tried to do it in a long time).
However, if this is a new installation your creating I suggest you look at the NBS v3, it's still in beta but we're only waiting for the templates to be completed before we release it. You might find it better.
