Re the alatixminor: It may be that it got some aphid damage - a few
aphid bites early can completely screw up a developing pitcher. Also
root damage can do it - since they were recently-divided plants, it might
be just getting over shock. Same for the S. psittacina - possibly there
are less roots? I would make sure it stays wet, and maybe put it in a
little more sheltered position for a while; the roots might not be able
to support the growth it's trying to make and need to regenerate.
good luck,
