Cf_ob_info and cf_use_ob cookies sent w/out secure flag

TrustedSite security scanner flagged cf_ob_info and cf_use_ob cookies being set without secure flag despite our domains being enabled as always secure in Cloudflare. Is there any setting in Cloudflare to enable these to be sure, given that the domain overall is always secure? Can this be corrected so that they are sent by secure, or should this be an exception for the scanner to ignore?

Thanks
