It's probably just different pacing,The manga has changed things, so let us see if things play out the same way. Well, in any case, we don't have the Chekov's gun moment happen from a prior chapter. Unless that brief charm magic was it, which feels a bit off.
I mean, it has legitimately changed things. Like his fight against Muzark has him never use this 'gift', and Muzark's own was different. So. . .It's probably just different pacing,
I think someone thought they wouldn't mention the magical gender change and it was the beginning of the next chapter.
