Hello Dooveackemb77
That’s annoying. None of the SBB ticket inspectors understands why SNCF is selling e-tickets which have to be picked-up at the station.
In Switzerland, you cannot retrieve these tickets, and they cannot be used as e-tickets. They are called e-tickets because you can order it online, but from a ticket check perspective, these are paper tickets and not e-tickets.
If you can, proceed as @Danhiel said, or cancel the tickets. If you travel with the PNR code in Switzerland, you risk a fine as you are seen as a passenger without a valid ticket.
Best regards,
Roland
