Well, since we know that Isshin was "powerless" during Ichigo's childhood, maybe it was the same with Masaki? She used her Letzt Stil and lost her powers, so she couldn't fight with Grand Fisher? That is just speculation, though.

Anyway, I can't say I don't like how the plot develops, but it does indeed feel a bit weird.
