ETH DevFee Always Rejected

Dear CoinFoundry,
 
i just wondering why DevFee always rejected since i start claymore miner.
have i miss the config file or something?
This is my config settings, maybe you could find anything wrong in it.

-ewal 0x1191AAdb9F7b9e321a755Fd50b4a0cFC3ABBCFB8.fenrir
-etha 2

-ftime 30
-wd 0
-r 0
-logfile noappend_history.txt
-tstop 85
-fanmax 80

Additional question
If DevFee shares always rejected, is claymore count it as -nofee 1?

Thank you.
