No respect of mannerisms

Ahh.. this bug is very specific in my campaign since the beginning, but it’s just not fixed at all, every time there's a new major update and I pay for it, I am sorry but I always found basic cohesion bugs in the first 10 minutes of playing, immediately. I report this bug because I just start over and over new campaigns, hoping that this bug was just a custom instructions problem, or this bug only appears once but no. It's a bug that annoys my immersive experience.

Here's the specific, consistent and annoying bug : one of my character in my party always calls me “Master (name)”. I want this specific and only this specific character to call me that way, yet since this character always travel with me, other characters has tendencies of calling me “Master (name)”. I am not a Master in their eyes, only in the eyes of the specific character I mentioned. Please fix that Franz always remembered that rule in the narration.
