It is telling me that I owe taxes for the first time.I received an adjusted W2 that says 'Less Cafe 125'. What does this mean and does is that what's affecting my return?

I received two W2s from my employer. One is original, the other has adjusted numbers in the area above where my name and information is at. It now includes a 'Less Cafe 125' dollar amount in between what appears to be how much I made last year and the amount of reported wages. Can you explain to me what that is and whether or not its affecting my return? I owe taxes for the very first time and I'm a little confused as to how the correct amount of taxes wasn't taken from my paychecks.
