Making my own fittings - sizing the hose

I have recently created a new fitting to be used for making hydraulic hoses using routings.  It is sized for Ø1¼” OD hose.  The hose I am using is the same one that came with routing, so it has the correct OD and many other sizes as well.  However, it’ll only let me pick the smallest one.  I figure this is a problem with my fitting, but I can’t find where I can specify the appropriate hose diameter.
