Master of Pyromancies not unlocking on PS4

I'm playing Dark Souls 3 on PS4. I spent hours to run for the Master of Pyromancies achievement, and well, I got the 27 spells.

The thing is: nothing happens. I don't get the achievement for some reason.

Any idea to solve this?

There are 28 Pyromancies in Dark Souls 3, at least according to the list on the wiki. One of those is a DLC item though.
