Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SD) - Gi1/1(D)
4 Po4(SU) LACP Gi4/31(P)
4 Po4A(SU) LACP Gi4/32(P)
10 Po10(SD) LACP Gi4/15(D) Gi4/17(D)

I also see this in the output of show ip interface brief

Port-channel4 unassigned YES unset up up
Port-channel4A unassigned YES unset up up

This Looks  You have  created Port-channel with 1 Port and later, you added another on to that port-channel 

Port  4 Po4(SU) LACP Gi4/31(P) 4 Po4A(SU) LACP Gi4/32(P)

Solution is :

config t

interface port-channel 4

shutdown <-- this will have service impact.

wait for 1 or 2min

no shutdown

should solve the issue.

Hi Balaji

Thanks for the reply. I just tore down the port-channel and rebuilt it and it's sorted itself out.
