Thanks for visiting the Community, kevinAVS.
I'd like to verify some information about the issue.
Could you share more details about " but stops at the next parent product"? Are you trying to change all the parent products into one? Also, you can attach a screenshot so I can give you a timely solution. Make sure to cover any sensitive information.
I'll keep an eye on your response. Thanks for dropping by, and have a good one.
