It's because of the history surrounding Aisha's introduction. You can see the original banners from May 31, 2016 in the spoiler here:

Notice how she is suspiciously absent from the out-of-game banner, but clearly present in-game. A couple of days later there was an update specifically to remove her image from the in-game banner even though her summon rate was still boosted.
