In this example: 650 _ 0 ‡aCooking‡zMexico‡zOaxaca (State) It is possible to have multiple subfield z. After linking the authority with the linker (ctrl-shift L), the marc tag looks like: 650 _ 0 ‡aCooking‡zMexicoOaxaca (State)‡9318501 Where the second subfield Z is removed. I then have to manually add the second subfield Z label back in. The authority linker should respect multiple subfields.
Forgot to mention this occurs in the advanced editor.
