yup, that is because you have sufficient spirit to summon the leader and that takes precedence over the Kotetsu that you can summon. Thus the game will automatically just add on another Kaede. Thus to be safe, you will have to wait for 9 attk spirit (Kotetsu + Kaede) or you can manually switch to Kotetsu as leader and then switch back.

That was the reason why I switched over to Susumu lvl1. saves me the hassle of switching since a attk spirit of 6 will summon Kotetsu as Susumu (leader) cant be summoned. He needs a 9. However there is a "danger" zone if your attk spirit is from 9-14 as Susumu can then be summoned but being only lvl1, he has low attk and def. Thus you will have to wait till 15 where both Susumu + Kotetsu can be summoned.

I initially wanted to just switch to Brekkie (max) as leader as she has high attck (3000) and sucky def (1000) but that will drive the def to total of 2101 which might be dangerous to some. I think Brekkie is good as there will be no "danger" zone at all.
