Mountain King Trophy Doesn't pop up.

Hi everyone.
I've been playing almost exclusively this game for the last two weeks. Now I'm trying to get the last two trophies for the platinum one. The problem with the mentioned trophy is that, after playing 14 stages (of 15 selected) i've score 349 points and the trophy doesn't pop up. Despite of this, I've played the las stage just in case I need to complete the tour to get this trophy but no way.
My question is. Do I need to play the 21 official stages to get this trophy? Or there is another kind of problem with this?

I didnt play all stages i only play majority of the mountain stages and off course a few more because it did it in Pro Team mode but it was not because i was chasing the trophy at that time, i got 302 points i think overall with Valverde. It pop up for me just after the overall standings etc was being showed and i press x to Continue after last stage.

But what is your ? PS3 or PS4 i did it on PS4 and havent got any glitchy trophies actually TDF games only got 1 glitchy trophy there make me give up it was TDF 2011 where you have to win first and last stage with same rider.
