Hi Mikhail,
I was able to reproduce the issue in your sample code.However,you can have the same settings for all the pages by using "PageCreated" event.
This event will be raised everytime when a new page is created and it will assign the same format to all the pages.
Here is a sample for your reference.
multiPage.zip
Please take a look into it and let me know if you have any other queries.
Regards,
Dhivya.
