Hey @brianfton,
I replicated a couple scenarios of what you may have done to find a solution. If you used the default paste option when pasting your Excel list (keep source formatting), that could be part of your problem since you'd have the Excel portion in a table and the added words as paragraph text. What I'd recommend doing is select your entire list, cut or copy, then paste as text (under paste options, it's the icon with the clipboard and A or select paste special and select unformatted text). This will remove any formatting from Excel that may be interfering with your sorting.
If your added text got included in the table and you're selecting all then using sort and your default sorting option is paragraphs, try instead highlighting the table, clicking on sort and select column 1 as the sort by option. I'd still recommend cutting and pasting the list as text to remove the Excel table formatting.
A third option would be to copy your entire list, paste it into Excel (I recommend using the "Match destination formatting" option), and just sorting in Excel.
I hope one of these solutions solves this for you!
