Review Detail of sennun in [BL] Strongest in the Apocalypse

I know he cross-dressed as a woman but we are told immediately he is a man but later chapters the narrator still calls him 'herself' or 'her', now that I think about it it seems like a grammar mistake, but still it happens very often it's not just one time even in the later chapters not the 2-3 chapters. The first chapters don't have a lot of mistakes but later it became common for even names to get shuffled a lot you can't tell who is talking and about whom. I know your new author but I think all these mistakes make the story very confusing, The problem with genders can be called grammar mistakes but the problem with names and you can't tell if it's the MC talking or the ML or the other party member, even the mc name changed a couple of times.
