Aspen normal and vacuum flash bottom oil's over-vaporization rate problem before entering the normal pressure tower

This is the simulated gasification section where stream 111 from the flash tower enters the atmospheric tower. It has shown that the gasification rate is 0.49. Why is the stream 222 coming out of the top of the tower 154.45, not the 0.49 of the feed stream 111?

Are flow rate and fraction the same unit?

The vaporization fraction is molar； Traffic is quality.
