_Meta file not finding files when nesting catch-all route in v4

[Firgrep]

Describe the bug A clear and concise description of what the bug is.

Nesting the catch-all route one level down. /nested-path/[...mdxPath]] seems it's not obeying the _meta.ts file properly anymore, type: "page", is not being respected.

Additionally, any nested paths inside of content are "not found". Without the nested path everythig seems to work fine.

To Reproduce Steps to reproduce the behavior:

1. Go to 'a nextra project that uses v4 catch-all route'
2. Nest the catch-all route one level down
3. Run the app
4. See error

Expected behavior A clear and concise description of what you expected to
happen.

Expected that it would be able to maintain the content folder integrity and its meta config.

Screenshots If applicable, add screenshots to help explain your problem.
