CoA mapping error

I have created one primary and one secodnary ledger.

Both have different CoA as follows:

SourceTarget1RL_COMPANY31RL_COMP32RL_LOCATION32RL_DEP33RL_DEP33RL_ACCOUNT44RL_ACCOUNT44RL_FUTURE35RL_ACTIVITY46RL_LOCATION3

When defining the mapping as per the below grid, i am finding the following error:

TargetSource RL_COMPRL_LOCATIONDifferent Value SetRL_DEPRL_DEPSame Value SetRL_ACCOUNTRL_ACCOUNTSame Value SetRL_FUTURERL_COMPANYDifferent Value Set

RL_COMP has only one value of 001

RL_LOCATION has four different values 001, 002, 003, 004

Attached is the screen shot for the error
