Water generation glitch

I created a new world for trying the new 1.10 features, one of the presetted ones, and used the locate command for finding a temple (/locate temple) for teleporting me away for finding a new village. So I teleported there and I saw that the temple was a igloo, I've entered it and I saw this strange bug, a bed with 3 water sources inside. When I broke the carpets, the blocks got updated and the water returned normal. Sorry for my bad english, hope I helped!
