Error? in kv calculation in RAM Connection

Hi everyone. 

I was calculating a joint in RAM Connection, and notice that, from my POV, is a mistake in definition of a and h values for calculation of kv.

In this picture you can see a beam seated on a column, with following dimensions:

Beam (mm) Column (mm)
Depth 1200 900
tf 11 11
Fillet 8 8

Now, the calculation shows that, for kv, considers the value a = 1200 and h = 900.

Now, according to Chapter G, a = clear distance between transverse stiffeners, and h = clear distance between flanges less the fillet at each flange.

As I see, a and h are inverted, and the flange thickness is being neglected.

So, for me, this means that a = 900 - 11 - 11 = 878 mm (depth of column that is the same as distance between stiffeners),

and h = 1200 - 11 - 11 - 8 - 8 = 1,162 mm (clear depth of beam).

So kv would be 13.75-

Am I correct or how should I understand this calculation?
