Page NaN display in the slider bar for the sized container embed mode

Hello,

I noticed that the Sized Container embed mode demo shows a Page NaN display pop-up in the slider bar at the following link: https://acrobatservices.adobe.com/view-sdk-demo/index.html#/view/SIZED_CONTAINER/Bodea%20Brochure.pdf

I work for USDA and we are using the sized container embed mode for our directives. Here is one of those directives: https://www.usda.gov/directives/dm-0100-001

Would you please let us know how we can resolve this issue so that we can use the slider bar to move across pages? We noticed this error about two weeks ago and have not been able to resolve on our end. We believe this may be within the embed code.

Please let me know how to proceed. Thank you.
