Problem with footnotes in a two-column environment

Question

A particular problem connected to the position of footnotes. In a book I work on there are several passages that include two columns (quote and translation). Sometimes these two-column-passages contain several footnotes. Therefore I had to use the \footnotemark option (instead of the plain \footnote option) and write the \footnotetext at the end. Now, if the two column environment includes a pagebreak, all the footnotes appear on the second page, even if the footnotemarks belong to the first page, and they have all the same number (see example). I did some research to solve this special problem but was unsuccessful. It seems that the fact that it is a two-column-environment causes the problems. So there are two questions: 1) how can I force LaTeX to position the footnotes of that environment on the page they belong to? 2) how can I force LaTeX to count the footnote numbers correctly? Thank you for any advice.
