Confirming Proper Format for Importing Multi-Select Fields in Beehiiv

I am trying to import / overwrite a multi-select field into beehiiv, the import is not overwriting the field. Before I submit a ticket I wanted to confirm what the proper format was for importing a multi-select field to make sure I'm not missing something there. For example I have multiple newsletters subscribers can subscribe to as a multi-select field, using the same syntax from the csv export I thought the correct way to format the field for import would be like this: ["BookBrowse Highlights (Weekly)", "Publishing This Week (Weekly)", "Book Club Newsletter (Monthly)"] However that is not overwriting, can someone please confirm the format is correct before I submit a ticket for the overwriting issue? FWIW this format seems to be different from what it was before (values seperated by || )
