Hi,
WYSWIG field type is not editable. There is a walkaround though - create a new field type out of the original WYSWIG field type and modify the new field type.

More info: https://docs.formtools.org/modules/custom_fields/core_field_types/

Just like the core fields, any module that extends the Core with their own field types cannot be edited via the Custom Fields module. You can use the module to browse their configurations to see how they've been set up, but you won't be able to update them. This ensures that you never make changes to those field type configurations which are later overwritten by updates to the module. [...] This module lets you make copies of any of these Core field types, which you can modify in whatever way you wish.
