Blueprint options always returning label

When using options in my blueprints, it always returns the label, no matter where I put it:

      rarity:
        label: Rarity
        type: select
        options:
          1: Common

and

      rarity:
        label: Rarity
        type: select
        options:
          Common: 1

give the same result of Rarity: Common and I can’t get Rarity: 1 without making both sides 1, which I don’t want to do for legibility

How do I solve this?
