hi! I'm not sure about sa border, pero sa missing Vaxcert records, you should try calling the LGU where they got their vaccines for assistance. I called the QC city hall when only my 2nd dose was registered, and they correct it within the day. Also, if you've raised a ticket sa vaxcert website, they might ask for it (siguro since you have uploaded the photo of the vax card there) so make sure to have your ticket number ready when you call them.
