Dialogues - frequency (too much)

At first I haven't noticed it, not that it was bothering me, but now that I've noticed it, I just can't get out this (bug?) of my head.

I’m playing a long campaign, and I'm always starting with a npc in my party. We are always together.

I just noticed, that, in EVERY, SINGLE, MESSAGE, there's a dialogue. Just every message. Simply as that. My npc is talking in EVERY single message. Sometimes it’s just for saying a little thing huh, nothing crazy, sometimes just talking about the surrounding, about nothing much very important but the npc in my party talks in EVERY single message, in a long campaign.

There's not a single message where the npc in my party just do actions without talking or making a comment. Now that I noticed that, it’s a bit unimmersive for me, as talking or having dialogues (even if it's relevant in the context) in every single message is simply not realistic. Fenix model.
