100% Kingdom Campaign bug?

[DaMaShI]

Hello there,

I've been trying to get the All-Star achievement on Xbox one by completing the campaign for 100% but appearantly I'm stuck on it because the last "chapter" won't unlock and I also can't seem to unlock the "Sir Brutus" spell in Kingdom campaign, although I've finished the whole game and even the side missions.
Is anyone else having problems with that or does anyone know/have a solution for this?

Greetings

Which level is locked? Have you tried beating the previous mission to see if it will unlock for you?
