[Dovecot] doveadm director remove error

[Xavier Pons]

 Hi,
with the version 2.0.rc3, when I try to remove a mail server from 
director list, get this error:

doveadm director remove 10.180.188.21
(null): doesn't exist

but the other commands are working without problem ...

doveadm director status
mail server ip                           vhosts users
10.180.188.21                               100     2
10.180.188.22                               100     3

thanks

Xavier
