Stats Armor
I don’t get what the problem is. You have a +5 in your back and a +5 in your offhand weapon (for your second set). If you don’t currently have that weapon equipped (the scepter/focus being your currently shown weapon set), you don’t get the buffs from that weapon or its upgrades.

As you can see in your screenshots, when you ‘equip’ your two one-handed weapons, your AR goes up to 10. When you ‘equip’ your two-handed weapons (that has no AR infusions), your AR goes to 5.
If you want to continuously have higher AR, ‘equip’ a weapon or weapons with AR infusions in all weapon slots.
Good luck.
