Exporting a Custom List

I'm trying to export the "Desert Summits - Zdon" custom list as a CSV. In addition, I'd like to include my completion dates for each peak. Is this possible?
I already tried the obvious: I went to the Custom Lists page, chose "export" for that list, chose CSV, then chose my name. I ended up with only my uncompleted peaks on that list.
