Hello robbx213!
Thank you for the report! The issue you are describing actually works as intended: if you are on the offensive side of the war and win/loose/sign a white peace - the truce should only apply to the attacker. I've noticed that one of the truces in your clip appears for both parties, could you check if they apply to the same war? Or maybe provide a save file with the situation you've shown in the clip? Save games can usually be found at: C:\Users\[USERNAME]\Documents\Paradox Interactive\Crusader Kings III\save games
