App Manager File size

After a backup, the size of an app in the App Manager "Apps" tab is different, usually bigger, than the backup up app in the "Backups" tab. I deleted the data and cache as a test before backup, still different size. After uninstall then reinstall the backup, it reverts to the original size, not what the backup was showing. Is this an internal tracking error our am I reading something wrong? Galaxy S3 CM11 w/ RTB Pro. Thanks!
