Alot a mixing of he and she
Wouldn't surprise me that the source most likely used gender neutral terms and they just went with he instead of they for some reason.
Then again i have seen people complain when translators use They instead of He/She.
Witch is dumb because i have seen several manga's where 10 chapters in the translators had to say sorry it was the opposite gender after all.
Having said that in all fairness this does feel like someone MTL this and just checked grammar but didn't check context or just ignored context.
