Updated the world from pre3 to pre5 and all water that was under any slab pushes the player toward it if the player is standing one block away in the farm (on the farmland not grass blocks), water on sugar cane farm, for example, is unaffected, not sure if it's related to the farmland or to the slabs.
For better visualization, the areas highlighted in red is an example where if the player stands on, gets pushed toward the water.
Update: Newly placed farmland and water are also affected
