For a 110v circuit to show this result you have a hot/neutral reversed and an open ground. It may seem implausible since an open ground by itself gets only one yellow light but that is what got the result when i switched wires on an outlet to test.

A 110 outlet wired for 240v also gets that result.

Best course is to have a fallback tester, ie - multimeter or wiggy and check your results.
