US Immigration from Sweden

We submitted the I-129F in December 2022 and just received an RFE. It says the submitted evidence do not establish each other's physical presence. It does say "as evidence to support the two year personal meeting requirement, you submitted booking details, text messages, boarding pass, pictures and intent to marry letters", yet it also says there is no evidence that we have met in the past 2 years....we did submit entry stamps from the passport but since they didn't mention them, I'm thinking they might have gotten lost or maybe we forgot to attach them.

It also says "Your form I-129F is missing page 5, 6, 7 and 8. Complete all items on the form as per USCIS requirements and attached copy of the petition and include your signature and date. If any item does not apply, write "N/A" even though we did submit those pages.

1. What more could we submit as proof of meeting? We did describe our meetings but perhaps we need to be even more detailed?
2. Do we resubmit the whole application or do we just resubmit these missing pages and the requested evidence?

Grateful for any kind of advice

In the email from the embassy they ask you to purchase a waybill from PostNord, which I have done, but on the US Travel Docs site, there's a VFS services "Premium Delivery" for the passport return.

Is it enough with the waybill? The VFS thing didn't even let my put my postcode in.

My visa is in transit to the Stockholm embassy, the doctor in Stockholm doesn't do K1 visas apparentely, the one in G teborg is closing according to an email I got from them and the new one from October doesn't have any information on their site, nor the State dept website. Anyone else who's done the medical in Sweden for the K1 have any information/help? Was it easier to go to Oslo or Copenhagen?

Thanks

Is it possible to after the oath drive to Canada with the certificate of naturalization and then fly to Europe with your EU passport? And then fly back with your EU passport and return from Canada to the US with your certificate of naturalization? Or would the US border question that when you return to the US driving from Canada? (Just trying to find out my options if I'm not able to get my passport before my upcoming planned trip.)

My oath ceremony is scheduled for August 30th, so I can't start the passport process until then. Which is my best approach to getting a passport in time for travel sometime in the second half of September? Do I schedule an appointment with the post office to get the process started as soon as the oath ceremony is over or do I wait and do nothing until I have a ticket and can make an appointment at the passport agency for an urgent passport due to traveling within the next 14 days?
