I am getting aclimated to understanding the revision sequence at my new job.

I am personally an administrator and the way we have our revision set up is

everything startes out being checked in as a life cycle of "WIP" (Work In Progress)

What I am noticing is after these files are checked into the vault as WIP and then

I go to check it in as a pre-release, and then released with a revision of 0,

in Solidworks Explorer I can only call up or view the pre-release and the released

but the WIP is removed from the revision history.  Does anyone know what setting is causing this?
