change Device Family

Hello All,

Hello all, I have a DC schematic and a Contact Development based on a SEL-351-6 relays. The DE who created the drawings assigned the wrong family to different sections of the Contact Development and to all the placed inputs, outputs, and ports on the DC Schematic. I am trying to reassign or change the family from RL_SEL-351-6_F to RL_SEL-351-6_035163A3D5-2x1_F. When I try to reassign the family to the correct part # I get the following error message: 

I have tried deleting the TBL Header and reassigning the family, does not work. I am thinking I have to delete all the IO contacts on DC schematic and start over. But I am hoping someone has a better idea?
