Hi Carrie and welcome to the forum.
PDFs can be difficult things - the way they are structured internally may bear no relation to what they look like and not all programs writing pdf files work in exactly the same way.
Over the years Monarch has attempted to address this problem by discovering all the hidden variations that have been made available so a later version may offer a better solution. Or it may not. If you are in a position to be able to share the file I would be happy to see what version 10 can do with it.
You could also pull it into the Adobe PDF reader and use the Export to Text facility to see what happens. It will lose the column formatting, probably, but it would be interesting to see what it does with the misplaced number 1.
Another option that people have found successful is to open the PDF file in a PDF edit capable application and re-save it. This will often create a better version that Monarch can work with. Not guaranteed though.
If any of these options are available to you try them and see what happens - we can then give some thought to the best way forward based on the results discovered.
