Mission planner not displaying in HUD the word Battery

How do I keep the battery indicator fixed…the word BAT??? because every time I enter mission planner it is no longer there and I have to put it back by right clicking on the hud and then from the window that appears I have to choose hud items again and then battery…and this every time I use mission planner.

It’s a bug, until it is fixed, just delete the line

<HudItems>Battery</HudItems>

from your config.xml
