Cannot equip Firefly Swarm

[HawkeSK]

Hey people !

I am trying to get trophy Hold still! and I am supposed to kill 6 enemies affected by Firefly Swamp

I did unlocked Firefly Swamp but when I went to mission (3 or 4) and i clicked Dpad down I have there only martial skills and I cant equip Anything else

I tried to click everything and do many things

What am i supposed to do to change it to orange still so i can equip firerly swamp?

Thanks

Unless youre level 20 you only have 1 of the 3 sets equipped at a time. You have to change it when you enter a mission from the safe house. Youlll be asked to choose one of your loadouts and in the top left will be your what Core you have selected. Thats how you change it.
