Custom Field Checkbox value renders empty if the values are randomly sorted
How to reproduce:
- Create a new Alphanumeric/Checkbox custom field
- Create new options with this specific order:
(Values are prefixed with '0' because back in the day, the advanced search would consider that, for example, "9" also matches "99", because of the sql query
custom_field like '%9%', but that's another topic.)
Result: the custom field renders empty.
PS: this seems related, but is not the same issue: #286 (closed) (and that issue is for 4.6)
