Default Site on User vs. on screen

SOLVED

Does the default site on the user take precedence over the default on the screen or vice versa?  We have a default site set on the user and then we also have this GFCYDEF(5), as the default on the Sales Order screen.  It seems that some users are getting the default but other users get a different default each time.  Any ideas on the workflow of this?  Thanks!
