Incorrect injector gas flow rate

Hi !

I have a question.

Bought a new 8890 GC system with 2 detector, when I set the flow rate through the column to 3 ml / min (for example) one channel displays the exact readings - 3 ml / min. But the other channel displays 23 ml / min, while setting the same 3 ml / min. With what it can be connected? injected the test mixture - everything works well.# I attach the photo.

Best regards, Azrael
