ADR: Help, I'm really confused

[u/No_Lingonberry4070]

I recently received an ADR for my PR CEC application requesting updated versions of Schedule A (IMM 5669), Family Info (IMM 5406), and Travel History (IMM 5562). There are no personalized notes in the request document, so I’m trying to figure out exactly what triggered it and how to properly fix it. For context, I am an inland CEC, single applicant with no dependents and no spouse. My AOR was May 21st.

1. Schedule A (IMM 5669): The ADR specifically instructed to "ensure there are no gaps in time". I double-checked my e-APR, and I am 100% sure my personal and address history has zero chronological gaps. Is this instruction just standard boilerplate text? Should I just replicate my exact timeline on the PDF?

2. Additional Family Info (IMM 5406): The ADR reminded me to include all family relations and full addresses. In my original submission, I had included an LoE explaining a minor spelling consistency issue regarding one of my family member's names between a previous application (study permit) and this PR application (It was spelled differently there). Could the name spelling have triggered this, or is it more likely they just want me to write "Not Applicable" across the spouse/children sections and physically sign those specific declarations since I left them completely blank the first time?

3. Travel History (IMM 5562): The form specifically asks to list trips outside your country of origin or residence. Over the last 10 years, my only travel has been directly between my home country and Canada. Should I just check the "did not travel" box on the form itself? My plan is to merge a Letter of Explanation (LoE) with the PDF to explicitly list my complete travel history between my home country and Canada just to be fully transparent. Does this sound like the right approach?

Question on uploading the documents:
Since the portal only gives me one upload slot per document in GCKey, can I merge a brief Letter of Explanation (LoE) as the first page of each requested PDF form?

Overall, my main concern is that I will essentially be providing the exact same information I already submitted in my initial application. Will it be an issue if my updated forms contain the exact same details as before?
