Pro Tip: A "ghost point" (red marker) is where your equipment will actually go if your data uses the wrong datum definition.
Why do these shifts occur?
Coordinate systems (Datums) are based on different mathematical models of the Earth's shape (Ellipsoids). Because different regions were surveyed at different times using different "best fit" models, a latitude/longitude point in one system does not align perfectly with the same numbers in another system.
