I have created a Custom Data field of the field type Alphanumeric Select with 3 selectable options - I want to be able to edit the options that can be selected, but when I try I get an error
"This option group is reserved for system use. You cannot add or delete options in this list."
What can I do to allow edits to the list
WordPress 5.5.8 and CiviCRM 5.5.1
