Multiselect with integer as option keys leads to panel error

Kirby 3

I believe this is a bug:

Using integers as the keys for options in a multiselect field leads to this error in the panel:

Cannot read properties of undefined (reading 'value')

after a option is selected, saved and page is refreshed.

I’m using Kirby 3.9.3 and my multiselect field looks like this:

jahrgang:
  label: Jahrgang
  type: multiselect
  max: 1
  options:
    2011: 2011
    2012: 2012
    2013: 2013
    2014: 2014
    2015: 2015
    2016: 2016
    2017: 2017
    2018: 2018
    2019: 2019
    2020: 2020
    2021: 2021
    2022: 2022
    2023: 2023

I also tried the hyphen style for options, that leads to the same error.

You have to use long notation for numeric keys: Multiselect | Kirby CMS
