Compass in boat

I noticed that while traveling around in my survival worlds on MCPE iOS iPad Mini, that whenever I go inside of a boat, my compass totally shifts its direction that it tells you to go, to the right. At first, I got very confused (and I got lost). Then I noticed what happened. It's very annoying and makes it hard to travel because of this annoying bug. Please fix it, it would be VERY appreciated by me,
