Notice: Undefined index: default in message_field_attach_form()

Hello,

I tried to manage the display of my message using display suite. I have simple message to display and only want to keep the Default display, but when I delete all the others display, I get an error message on the message edit page :

    Notice: Undefined index: default in message_field_attach_form() (line 505 of D:\***\Drupal\sites\all\modules\message\message.module). Backtrace:

    message_field_attach_form('message_type', Object, Array, Array, 'en') field.attach.inc:580
    field_attach_form('message_type', Object, Array, Array, 'en') message.admin.inc:297
    message_type_form(Array, Array, Object, 'edit', 'message_type') 
    call_user_func_array('message_type_form', Array) form.inc:798

Any idead how to fix it ? Is message not compatible with display suite ? I thought it was as it integrate entity API and should not be different than all others entities that perfectly works with DS
