Water sources of villlages fields

Hey !

Last time I created a new map and /tp randomly on the mpa, I found a savanna village. This village was strange, all the fields were full of water, like the water sources destroyed crops everywhere, or they are just not moving, like if they were solid bloks.  Here's some screenshots.

If you wanna test yourself, here are the seed and the coordonates:
