Funky output from SQLCMD.EXE /L

I have a Clustered environment - both nodes with SQL 2012 on Windows 2012 Server.

On the Passive node, SQLCMD.EXE /L lists the found servers as expected, e.g.,

Servers:
    MYCLUSTER1\CLUSTER
    ....

However on the Active node, it gives some strange output, i.e.,

Servers:
    ;UID:Login ID=?;PWD:Password=?;Trusted_Connection:Use Integrated Security=?;
*APP:AppName=?;*WSID:WorkStation ID=?;

Anyone know what this means?

Does this mean my cluster configuration and/or registry is messed up?

Thanks.
