If you read her profile entries it explains it, but she's currently in Chaldea through shenanigans. Originally when she was summoned early in the project the Chaldea system was incomplete and unable to support her for long, so she created a duplicate puppet to act as a master in order to maintain herself and cheated the system in this way. Because of her irregular/flawed summoning she's prevented her from being able to fight like a Servant, but if Chaldea is able to summon her the usual way then that version will be able to act like a standard Servant and would have the proper summoning support of the Chaldea system.
