pdf file with multi pages can't parse fully,the second page's tables can not display

[cheneygan]

a pdf file has tow pages ,the first page has 3 tables,the second has 2 tables.
but when use camelot.read_pdf ,with parameter： pages='all', the result return only 3 tables,not 5 tables.

import camelot
tables = camelot.read_pdf('a22.pdf',pages='all')
tables

why return only 3 tables? thanks
the source pdf is here:
a22.pdf
