Do not worry, you are not alone. My application was returned 2 times too, YES, 2 times die to missing information that I do not know. They said they cannot verify my status before becoming PR which is very strange.
these are my timelines
April 25 submitted - Application Returned May 9, 2023.
May 9, 2023 I resubmitted it the same day it was returned and on May 31, 2023 they returned my application for the same reason.
i do not know what to do anymore as I do not know what exactly they want.
November 10, 2019, Worker
May 29, 2020 submit to extend work status.
July 10, 2020 submitted PR
August 10, 2020, eligibility for PR has been granted
August 11, 2020 submitted bridging work permit open
October 4, 2020 became PR
No decision for Work permit extension and bridging open work permit. My PR was granted first. I contacted IRCC Edmonton for these application to be withdraw as I am already PR. Nonetheless all of these application are cancelled in their data base even I did not request for withdrawal.
I am on work permit from November 10, 2019 to October 3, 2020. I Did not travelled outside Canada since I landed in 2019.
I do not know why they can not see this in their data base. They can easily run a thorough search in their system and it will trigger my records.
furthermore. I received my ATIP request from CBSA two days ago. It shows no record on file for my exit in Canada. This may help my situation. I will resubmit my application via paper.
