Um, well..
What I was going to say is, for some reason the default disklabel
doesn't pick up your partitions (it should also show the EFI, but
doesn't).
As a quick-and-dirty fix you cold try and change the partition ID to
something that's picked up by the default label.
3f929abc-650c-4237-af34-2027ddc585e5 should work.
For a proper fix, find where the partition IDs are kept and add yours.
(With an MBR disk you could force feed a handcrafted disklabel but
that won't work here because on a GPT disk without OpenBSD partition
the disklabel and the primary GPT share a physical sector and that
won't work.)
