Well, I really don't see anything that seems like it should make any difference. However, I have noticed that, for most readers, the semantics that you can add for most html files within the epub, rarely serve any purpose and can on rare occasion cause problems. The only semantics I've seen that are in any way useful are cover and toc.
Just to rule it out, remove line 87 of your opf, the one that references dedication.html as the dedication page. After removing this line, save your epub and try again and see if anything changes and let us know.
