plank does not remember position of items every time restarting

[Viet Ha]

plank version 0.10.9.1481 on Ubuntu Gnome 15.10 gnome shell 3.18

Every time I restart plank, it does not remember position of items from the last time. I tried turn on lock items but it also does not work, after restart, lock items turn back to off. And in dconf, net > launchpad > plank > docks > dock1, dock-items entry is just a blank array []

Here is my plank -d:
