A few questions:
-How much oil did you add when you changed the oil?
-How much was drained when you removed the filter?
-Are you getting a white puff of smoke on startup?
-Have you driven the car since the oil change, not just idling?
When you removed the oil filter, that should have drained about a quart, and one bar on the digital gauge is roughly one cup (8 oz). Driving the car after an oil change will also affect the oil level as the oil circulates through the engine. A white puff of smoke will indicate if an overfill is actually affecting the AOS.
