Sheet Index Seed

I am trying to create a seed DGNws file so that all new WorkSets get a base Sheet index in them that contain project properties and folders.  I tried using the variable _USTN_WORKSETDGNWSTEMPLATE but it creates a DGNws with two indexes in it (see below). Wouldn't be an issue if I could delete one of them and rename the other but trying to do anything in them causes a crash.  Any thoughts on how I could create a seed DGNws file?
