Able to crop image but images in style format are getting saved as black block images.

I followed all steps required but sometimes when I resize the cropper and save image it crops image correctly and saves correct "Original" image but small, thumbnail, large this variants of same image are getting saved as black color block.
image style types: small, medium, large, thumbnail

has_attached_file :header_image, styles: { small: "720x300#", medium: "1440x600#", large: "2880x1200#",thumbnail: "360x360#", original: {convert_options: '-strip'} }, default_url: "/assets/missing1.png", hash_data: ":class/:attachment/:id/:style", path: '/:class/:attachment/:id_partition/:style/:hash', hash_secret: PAPERCLIP_HASH_SECRET crop_attached_file :header_image, :aspect => "12:5" validates_attachment_content_type :header_image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]
