The 'rel' and 'target' checkboxes have return_value of type strings yet the schema is defined as boolean which is resulting in not accurately outputting correct attributes when link is rendered with these options checked.
For a uri subfield type, set the display setting to formatter type 'Link'. Set the checkboxes for 'rel' and/or 'target'. Add an entity with this field value and observe rendered output for the atttributes are not using the return_value defined in settings form which means the form is saving the settings a booleans.
Change the schema for these 2 options to string.
