A couple of points ... the 10 pages originally filed is the actual return. The PDF you could download recently includes all the fed/state/program worksheets that are not part of the actual tax return so don't let that worry you ... the IRS got what they needed. Eventually they will process the return so check the IRS site once a week for a progress report.
As to the issue of why the amended return is not the same is probably due to program updates and/or you accidentally clicked on the amendment process a second time. Again this doesn't affect the return you already filed.
