Hi Gregg,
Login to RSA1, click on TOOLS and choose 'Conversion of Logical System Name', here check what is the target source system and what is original source system. May be that will give you a hint as to what is the mismatch. This is generally where you maintain the target and source system names so that when you transport source system related objects their source systems gets changed automatically to point to the right source system.
If entry is wrong here, then it might be requried for you to edit it and then reimport.
Hope this helps,
Regards,
Manohar. D
