DRBD-MC version: 0.8.8 (jar)
DRBD kernel version: 8.3.8.1
DRBD userspace utils: 8.3.8.1

Steps to reproduce the problem at my cluster:
- Edit /etc/drbd.conf, on both machines add section:
  handlers {
     fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
     after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";
  }
  inside the resource section

- run 'drbdadm adjust all' on both machines
- start DRBD-MC on local desktop, connect to cluster
- operating mode: Administrator, Advanced
- at this point, the config is still there intact, but DRBD-MC doesn't
show any handlers section. only resource, net, disk, syncer
- make changes to any part of drbd config through MC (in my case,
checking the "Use rle" option for syncer)
- apply, and watch my config files being overwritten with new config,
now without the handlers section at all
