Master Planning deleting manually approved planned purchase orders and removing the notes

Why is Dynamics 365 Finance & Operations Master Planning deleting manually approved planned purchase orders and removing the notes attached to them?

We are experiencing an issue where approved planned purchase orders are being deleted during a Master Planning run. In addition, any notes attached to these planned purchase orders are also being deleted. We expect approved planned purchase orders and their associated notes to remain intact unless they are explicitly canceled or removed by a user.

We are on Version 10.0.47 and using planned optimization

Could you explain:

Under what conditions does Master Planning delete approved planned purchase orders?
Is this standard system behavior or a configuration issue?
Are there planning parameters, firming settings, coverage groups, or action message settings that could cause this?
Why are document attachments/notes deleted along with the planned purchase orders instead of being retained?
Are there known issues, hotfixes, or best practices to prevent this behavior?
