Meaning of Inlet Boundary Condition during 2D modelling

The inlet boundary condition makes sense in 3D modelling. But for 2D modelling. the model is really just a slice of the 3D model, so units should not be "kg/s" but rather "kg/s/m" for mass flow. So I do not understand why the Inlet boundary condition has marked kg/s for the normal mass flow rate.
Is this an oversight, or is this implied somewhere?

Hi,
It is assumed that the 'slice' studied has a depth of one length unit.
All inputs behave like this. As an example, a volume force is given in N/m^3 also in 2D.
