I had to mail my Canadian tax return. The PDF downloaded for mail submittal had around 10 pages. However, the saved PDF in View All Tax Returns is around 50 pages, why?

- I followed on screen instructions and attained the 10 page submittal
- When I log back in and go to View All Tax Returns, all my previous years PDFs are available including 2022.  All are around 50 pages.
- Did I mail in the wrong output?
