These are just warnings: since you have a force constant of 0, it doesn't
really matter that the phase is not 180 (which it should be for a real
improper). In the past, someone thought it was important to notify the
user when they were entering dummy parameters (with PK=0), but this may be
oversolicitous. But you can just ignore these messages.
