I think you have identified the problem yourself. That is you are attempting a mass Action (PATHCOPY) from a group basis to a segment basis.
I think PATHCOPY similar to BULKCOPY but more specific still requires the message structure definitions inbound and outbound be identical.
In this case they are not.
The solution might be to do a field by field action (probably COPY). Don’t forget to put the inbound group iteration counter (for example %g1) in the segment position of the outbound address path.
