IVE: Instantiated function interfaces renamed after re-load

the "Clients" function type is instantiated twice (Client 1 and Client 2)

However there is a RI mismatch. It was correct when I saved it (the "End Transatction" RI was properly connected to the block named "Transaction". But after saving/reloading, it is disconnected and appears as "RI2" on both instances

(And you can see errors in the bottom: "Connection failed")
