poe2 - witch - minion spells/count bugged after equipping/removing spirit armour

I noticed this after I put on a body armour that has spirit on it - this is easier to reproduce with the unique body that gives 100% spirit
I increased the minions that I have with the extra spirit, but then swapped out the gear that gave me spirit. My minions lost count, however the spells that I could use remain.

My set up.
Skeleton arsonist - x2
Skeleton mager - x2

Put on the unique armor.
Increase minions

change / increase minions in gem tab to:
Skeleton arsonist - x4
Skeleton mager - x3

remove the armour, the spells you can use with the above minions still shows 3 for frost and 4 for fire. the minions still sometimes stay but if they die then the minions go back to 2,2 however the spells stay at 3/4.

I tested this with some other body armors and was only able to really reproduce this with an item that gives 80+ spirit since you need a bit to add more than 2 minions in the Gem menu.
