I'm not completely sure how you have static /48 but dynamic /64. Can you
not assign yourself a fixed /64 from the /48 if that's what you want?
Presumably the sister is getting allocated a /64 which varies, but always
comes from the same /48.
Ah, yes. I misread the OP.

Seems to suggest that you should get a /56. Does the OP get a /64 from
the same /56 each time or is it a different /56 each time?
