The only way this can happen is that either the install is somehow not correct/complete or you accidentally set album themes for certain albums. Check that on the album in question, there is a drop down menu to set that on each album edit page and also on the themes page itself.
Regarding Zenpage: Would you mind to tell what you tried and what did not work? Not that it can everything or not that I can fullfill all wishes (nothing wrong with using Wordpress if that fits better), but I still would be interessted in the details.
