Does it work with unique=false ?

[pablo-sg-pacheco]

CMB 2 saves multiples meta fields using unique = true as default. It serializes the values. I don' want that and i'm using unique=false, but it creates this error:

PHP Fatal error: Uncaught TypeError: Argument 2 passed to PW_CMB2_Field_Select2::sort_array_by_array() must be of the type array, string given

Is there a native solution for this?
Thanks!
