¿Romance club fallando?

Hi girls, does anyone know why this is happening to me? I'm playing Hunting You again, this would be my third time (I'm doing it to get 100% with Ellia).

Previously, in my second playthrough, I managed to reach the black mirror in the locker room, but I just realized that now when I go down to the diamond mirror, I get stuck at 2%. Similarly, with Sofia's 10 Wishes, I finished playing it for the third time today, and in my second playthrough, I made sure to buy all the outfits. I noticed that the mirror (which was previously black) turned into a diamond and was at 3%. (In this third playthrough, using Diamond Rush (since it doesn't show whether the outfit is purchased or not, I bought them all), it still stayed at 3% and didn't go up at all.) The same thing happened with I Love You Vol. 1. I also played this story three times, bought all the outfits, hairstyles, makeup, etc. (just like with the other stories), and it was at Black Mirror. Now it's at Diamond Mirror 2%. Does anyone know why this is happening?
