I don't think that's gonna help. Even Calendar_pages.xml from Manila_Calendar 1_0_20121928_0 and Manila_Calendar_2_5_20142522_0 has the exact same entries. I think it may be a mode9 issue, as there are mode9 references in Calendar_pages.xml, but I don't know much about mode9.

From Manila_Calendar 1_0_20121928_0 Calendar_pages.xml:
