Not receiving afterglow eureka

Hello all I hope everyone’s day is well. I’ve done the eureka challenge dream warehouse trial on hard difficulty last night, the night before, and just now tonight, specifically for the afterglow head eureka, and for some reason I am not receiving it after three nights of trying . I have searched online but can’t seem to find an answer. Does anyone know if it depends on the amount of times you fall to the ground and ‘die’ or depends maybe on the time limit within which you finish as to what eurekas you get as a reward? I get other eurekas when I finish the challenge, just not the afterglow head eureka I’d really like. Any suggestions or advise is greatly appreciated, thank you 🙏 😊
