Fight at Vranik Armor in cutscenes

So because i’m a smart Henry, before I went into Vranik, I put all my stuff in either the chest or on the horse. So when I got back to Rattay, I could get my OP Lords of Leipa armor back for the next fights.
However, almost all of the cutscenes after that henry wears the armor you can pick up from the armory in Rattay and rides a standard horse (not the horse i own). Is it because those cutscenes are fixed or is it a bug as well?
