Can't access special events

I turned off revenge of the cartels and now the option to turn it on is missing, also I can now not play midnight cairn or guardian breach as they are locked also.

Revenge of the cartel event is over.
To play maliwan takedown you must have finished story with the character you are playing

I have finished but it is still locked. It gave me the mission I just can’t open the door.

There’s two levers: the one on the right switches between true and levelled modes; the one on the left opens the door. Make sure you’re using the right one. I believe there is also a minimum level requirement?

Tried both, they won’t budge
