Is it possible to achieve 100% game progress? (PS5)

[Ceridane]

 

First of all this is not trophy related but as a completionist its been bothereing for a while. As you can see in the screenshot mine is stuck on 66% and I already earned the platinum trophy for the game.

 

From what I know the game progress on PS5 is just for story mode and I already have 100% on all 3 main routes. So I'm wondering if this is glitched for everyone or there is something else is needed for 100%

 

If someone on PS5 have been able to get 100% on the game's page and knows what else is needed it would be really helpful.

 

Thanks in advance.
