I'm not sure I understand the math here.
Evocation grants one Evocation specialization, Thaurmaturgy grants one Thaurmaturgy specialization, you have four focus items from Evocation and Thaumaturgy, and you took two refinements.
You used a refinement to add earth to your Evocation repertoire, used your Thaurmaturgy specialization to add one to your Divination control, used a refinement to add two specializations to evocation, three focus item slots for your wand, and I assume you used your last focus item slot for your Warden Cloak, I understand those, leaving you with your one evocation specialization.
Unless I'm missing something you have an evocation specialization that you are not using.
