Summons not working properly

I have a Skeletal warrior sceptre equipped in my offhand. I am dual-wielding a wand in the main hand. I can summon the first two skeleton warriors for free. I have EVERY gem slot disabled, removed all my spirit and skill gems, but I cannot summon more than 2 skeletal warriors. My spirit shows as 385/385 but if i try to increment the skeletal warriors to 3, I get the error that says not enough spirit to summon desired amount.

Another thing, if i try to use wolf pack, I cannot right click the skill. Doing so does nothing, the wolves do not summon. I am still at full spirit.

However, if i remove the wand and make the sceptre the main hand weapon and have an empty offhand, I am able to summon the skeletal warriors, using my spirit appropriately AND now Wolf pack is activated.

I am playing as a Shaman. Let me know if any other information is needed.

This is happening to me as well. I hadn't tried putting the scepter in my main hand. I've mained witch summons for so long I didn't even think of that! I found if you unequip and reequip the scepter to the same hand it also fixes it though watching for unsummoned skeles in the middle of combat is not easy :P
