Yeah, i'm having this problem now with Gale. During events despite my character being the farthest left spot and me playing my guy, dialogue options and cinematics show Gale during narrations, and he makes facial expressions as if its my character. I first noticed this issue when I was at camp getting ready for a long rest. I was talking to my companions and I noticed that Gale's character window was moved to the farthest left spot despite me not having moved it. (i noticed that particularly because I read your post an hour or so before this happened).
