No rewards for Sekhemas Trial

I've been trying to get my ascendance points and, finally, completed the trial required for that... But when I interacted with the statue to get my points, they just disappeared, should I need to do the trial all over again?

have you already donr the trial once and picked the ascendancy, and you're getting like the 3/4 point? IF that's the case the trial is probably not high enough of a level the key that opens the trial will tell you if it's going to give ascendancy points or not.

Yeah, it's my 3rd point, I'm level 75 now

it's probably the ilvl the the key you used.

it's a 68 level key...
