Workgroup PDM lifecycle - check in problem

Im having a problem Within The check in of Assemblys.

I have the life cycle Set up  Underchange>Underapproval>Approved>Released

IFfi have an assembly in the Vault as "Under Change"

If i check in another assembly that uses the same parts and some new, It adds the new parts as "under change" but the parts that already exsist in the vault. are greyed out and have "underapproval" in the Lifecycle box. meaning it bumps them to the next stage in the cycle. Surely these should just Stay the same.

Thanks Joe.
