Soldier level up orders?

not sure if im missing somethink but it wont let me use soldier level up orders on troops that i want to use them on (tier 2 level 4 classes)

or on any trooper

The tickets doesnt exist anymore. You can use them to get another perk or to reroll, thats it.

I think that it requires TWO to get from 4 to 5… not certain :thinking:
