Thank you for contacting us.
Currently there is no way to edit the choices field except recreating the module. However I can offer you simple and efficient workaround. You can create a custom classification
similar to tags and use it instead of the choices field. To do so create the classification and then edit your module, add classification field and from the "Type" dropdown select your classification. You can add and delete as many items in the taxonomy as you want and there won't be any need for recreating the module.
Feel free contacting us if you need further assistance.
