I will have to disagree. While the stories in mythology sometimes contradict each other, Rick Riordan has said that he picks one version of the myth he likes and sticks with it. While some of theses may be explained in later stories (making them not plot holes), if they were really intentional he wouldn't be trying to fix some of them.
