Well I just looked up your shell and see the problem. Your shell was not designed with a wrap liner in mind. You really need a tongued liner to provide the support up front and evenly distribute the pressure along your shin. The upper cuff of a 2-piece shell does not have enough overall height/length along the shin.
My rule-of-thumb is that a wrap liner is only used as a replacement for an OEM wrap liner. If the OEM liner has a tongue, then your replacement liner should have one too. You "might" be able to get away with using a wrap liner IF it's very stiff and/or has additional support (i.e. plastic) added over your shin area. In fact, there's an idea for a fix if you don't want to replace the liner, try having the fitter add the extra support by using the plastic outer piece from an old tongue. It's a hack, but I'm pretty certain that the lack of support from the wrap liner is what's causing your pain.
BTW - What model Intuition liner do you actually have? The "Intuition Precision High Wrap" is not a current model, nor one that I recall.
