Predator Vision Achievement

Hello everyone, I just wanted to get your thoughts on why I have not received the predator vision achievement.

I have already got Apex Predator. My understanding is that you can complete Predator Vision by doing the same missions with the same parameters (T1 difficulty / 30 or over OPFOR) just at night.

I have done all of the missions with these parameters at night and have yet to get the Predator Vision achievement completed.

What do y’all think I’m missing? Cheers!
