Led indication for changed address could be wrong

Configure slave by config.nxd with controlled release of communication.
While DPM Bus state is Off, send RCX_SET_FW_PARAMETER_REQ to set new bus address.
Send this packet 2 times with different address values (for example 5, then 8).
After setting Bus On slave is using bus address 8 as expected.
Connect a master to start cyclic communication.

Communication starts, but MNS led is flashing red, should be green.

Send RCX_SET_FW_PARAMETER_REQ again to set station address 5.
Now MNS led turns green.
