For that page, you need to extend the range that it searches for columns with -cgr:
k2pdfopt -fc- -cgr 0.5 11.pdf
Use -sm to see how k2pdfopt is parsing the file. You cannot use -cg .05 on this page because it will break the text incorrectly--the default value works better. There may not be one set of settings that works for the entire document, unfortunately. You might like the results from -mode fitwidth better (in terms of consistency, at least, but maybe the text will be too small).
