Trial of Chaos 4th ascention issues

good evening.
i tried several times to do the 4th chaos ascension but every time i finish it and it doesn't give me the 2 points for the ascension. i spoke with the trialmaster both before going to the fountain and after, but it doesn't give me the points. i tried with 78 and 80 maps. it gives me the pieces for the megaboss but not the points. i'm
waiting for news thanks
