In MN 115 it is said that Stream Enterers are incapable of committing certain actions:

• Seeing any sankhara as permanent, satisfactory, or self.

• Killing their mother, their father or an arahat.

• Injuring a Buddha.

• Creating a schism in the sangha.

• Taking another teacher than the Buddha.

  This list seems to imply that stream enterers are still capable of committing other bad actions. But there are numerous instances in the suttas that seem to say that stream enterers Possess Perfect Morality and are thus incapable of breaking the five precepts. See for example AN 9.27

  And a noble disciple’s ethical conduct is loved by the noble ones, uncorrupted, unflawed, unblemished, untainted, liberating, praised by sensible people, not mistaken, and leading to immersion.

What is the explanation for this apparent contradiction? Am I misinterpreting the suttas? Could it be that one of them was a later insertion? Thanks in advance for your answers!
