Multiselect doesn't store values but the keys

  1. You can’t store the values, unless you use your values as keys in your blueprint.

    options:
    "Interactive": Interactive
    "Print": Print
    # etc.
    

Edit: if this doesn’t work, there is the long version below.
2. You can get the values from the keys via the $page->blueprint() method.
3. You could alternatively store your key-value pairs in an array in your config and fetch via the options() helper.
