How to add mutators past advanced?

Gears 5
#1

They are locked to me. Any clue? This in custom horde

#2

Beating horde with the 3 mutators on should unlock the fourth for that map.

#3

Oh so it is map locked too? That is why I have all of them lock, I cannot finish a horde map without getting disconnected -.-

#4

Yeah its a pain atm with server issues. Personally i would have thought doing it on any map would unlock the next one but currently it doesn’t work that way.
