Spirit keeps disappearing a few minutes at a time

I’m playing a witch, which starts out with 100 spirit, I’m using 65/100 spirits for the archer minions, also carrying a scepter to summon warrior minions without cost of spirit. I’m left with more playing time without having spirit than having spirit. The spirit number disappears from above the mana pool for minutes if not longer at a time. Each time that number disappears, so does my minions, and my minions won’t summon again until that number reappears. The spirit number disappears and reappears at random, including if I’m in a middle of a boss fight. I’m playing on the Xbox Series X console version. Big report reference number 2,939,507,423.

I figured it out, I was in my second weapon set which my skeletons weren’t activated in, also I realized I was getting to 100 spirit from the scepter, which means when I was in my 2nd weapon set, I had no spirit to be able to summon them.
