Gigantic Following will not load all minions

I have one scepter that Grants Skill: Level 7 Skeletal Warrior Minion. I have the base 2 for free.

I have the Skeletal Sniper with two activated.

I have a Spectre: Auadrilla with one activated.

I have Skeletal Arsonist with one activated.

When I was able to get the Gigantic Following passive keystone, I was expecting to up my army. What happened is the following:

Spirit went up to 111/205 and the Spectre: Auadrilla and the Skeletal Arsonist both are not active. Hovering over the red exclamation point it states: Not enough Spirit to summon desired amount.

Is the Gigantic Following giving the wrong text? It currently states:

25% reduced Reservation Efficiency of Minion Skills
Your Minions are Gigantic

Should the first line read:

25% increased Reservation Efficiency of Minion Skills


After removing the existing count for the Spectre: Auadrilla and the Skeletal Arsonist, the reservations are higher to add one minion than the gem reservation shows.

For an example of the numbers, Skeletal Arsonist has the gem RESERVATION: 42 Spirit. When I hover over the + to add a minion I see Reservations: 56 Spirit.

So now I don't know if the passive keystone description is wrong or is not operating properly with the current description for the keystone.

Please ignore this. I took the working the incorrect way. Reduced Efficiency adds more spirit needed.

The keystone Lord of Horrors has 12% increased Reservation Efficiency of Minion Skills. This keystone reduces the spirit needed. This is what I was thinking for the Gigantic Following keystone.
