Thank you for contacting Microsoft Q&A.
I’m truly sorry for the frustrating experience you’ve encountered while trying to attach a OneNote page to a Teams assignment.
I’ve taken some time to look into this more deeply, and I came across a post from 2023 that describes a similar situation.

According to that thread, this appears to be a known limitation Teams assignments currently do not recognize sections inside Section Groups or manually distributed sections, even if they exist in each student’s notebook.
Unfortunately, I don’t have access to an education tenant to test this directly, and as of now, I haven’t found any official Microsoft documentation confirming whether this limitation has been resolved.
Workarounds You Can Try:
You can try using the OneNote Class Notebook add-in for Teams to distribute pages or sections to your students’ notebooks. This add-in allows you to distribute content to any section or section group, including those that may not appear in the Teams assignment interface.
Alternatively, you can use the OneNote Online app to distribute pages or sections. It also supports distribution to sections and section groups that are not visible in Teams and may offer more flexibility.

That said, I’ll continue monitoring this issue and will share any updates I find. If Microsoft releases new guidance or changes this behavior, I’ll make sure to let you know.
Thanks again for your patience and for bringing this to our attention.
