I was going to add PPP (protect) Magnusdotter as being the correct LNAB, but that's not one of the choices.
My understanding was just one name is preferred in the LNAB field - e.g., Magnusdotter, not Magnusdotter Malstaatten (and I'm not sure what Malstaatten is... the place?). ''update - Eva's reply to Helmut answered this - not sure how I missed it before''
Once the correct LNAB is determined, it should be protected prior to proposing merges to ensure the merges go into the correct profile.
