Normally after the PPR, PP must be send within 30 days as they have clearly mentioned in the email so you did that by sending it in a month September and again you
requested PP back in November from NDVO for foreign travel I guess, the following below may help you:-
# Send again your request to the CIC inquiry about, resending your PP with the reason.
# Do not send PP unless requested by CIC.
# Wait for their reply before sending PP with your old PPR letter.
# If you have traveled abroad then attached the supplementary form filled with an old and the new travel history along with the duration of stay.
Good Luck
