Problem with loading images from frontend user to author

Hi, I need help because in your template purchased Skywarrior, when a user registers user permissions by default are those of Author, just that I need to set them to Collaborator, also to customize the image file of the profile, but when from backend WP apply this change, the setting is not saved and is always the default one that is Author.

Please help me.
