This is not a bug. It is intended behavior. The autocalculate option attempts to calculate the depth of the water table based on the elevation of your location to determine the depth of the deep ground boundary condition. If the predicted water table is higher than the deepest element of your foundation, EnergyPlus will modify the depth to be one meter below your foundation. You will see this warning (it isn't an error) just to let you know that the water table is really close to your building and EnergyPlus is making an exception to allow Kiva to work properly.
Some of your locations are below sea level resulting in an initial estimate of the water table being above grade (e.g., -0.919 m).

Here is the full warning:
** Warning ** Foundation:Kiva="SLAB FOUNDATION", the autocalculated deep ground depth (-0.919 m) is shallower than foundation construction elements (1.500 m)
** ~~~ ** The deep ground depth will be set one meter below the lowest element (2.500 m)
