Ascendancy points bug [POE2]

I used a trial key that says it grants ascendancy points. I completed the Trial of Sekhemas, starting with the Test of Strength and then the Test of Will. After completing the trial, the ascendancy altar was highlighted, telling me I could claim points. However, when the UI popped up, I was unable to gain any points.
I restarted the game to resolve the issue, but the trial key was then returned to me.
