Numeric Permalinks disrupting sub-pages

I have set my permalinks to the ‘Numeric’ setting.

For example, for posts it comes up:
domain.com/archives/123

For pages:
domain.com/page-name

But with sub-pages, all that comes up is the parent page. I’ve tried Googling and was hoping someone could tell me if there is a way to fix this while using the numeric permalink structure.

Thanks!
