MEGS_Log detected an inconsistency between either the depth (top or bottom) values attached to a unit, or the previous interval, or the thickness of the interval.

Note that not all schemas have top, bottom or thickess fields.
Review the depth and thickness information for the given interval (and possibly the previous interval) and try the operation again.
