According to the website (see link below), that is only achieved if you score 5.0 in three abilities and 4.0 in one ability.
Your scores are 5.0 in two abilities, 4.0 in one ability and 4.5 in one ability. I believe this could be an issue. I am sorry, but, it seems that you may have to give your test again.
Please be positive. You're so close. I'm sure you will get the required points if you take the test again. I know it would delay you application for 2 months but that's nothing compared to the time the whole process (PR) would take.
