Help With US 2016 World Stamp Show Issues

I purchase the annual Stamp Yearbook with Collectible Stamps (I'm pretty sure these use to be called Mint Commemorative Sets) ~ it is simple, mounts are included, and singles are included so I'm not having to purchase whole sheets.

This morning I'm editing the Steiner pages for U.S. 2016 (I need to adapt to the 9x12 inch Harris Liberty page size, and sometimes the stamp packet will have a strip while Steiner has a block, or vice versa), and I'm encountering this situation …

• Steiner has two (and only two) spaces for World Stamp Show 2016;


• Stamp World (dot com) shows two (and only two) issues for the 2016 World Stamp Show New York, light red and light blue;

[*]The USPS web site shows two (and only two) issues for the 2016 World Stamp Show New York, the same light red and light blue color;

However, the 2016 stamp packet has four issues for the 2016 World Stamp Show New York, as shown below.

What am I missing?

You show:
Scott 5062-63, issued in 2016 at the time of the show, and
Scott 5010-11, issued in 2015 to advertise the show.

I will add the sheet size for the one at show was very large.

Thank you very much John Becker. Looking at my 2015 pages I see that there is a space for those two stamps (which I can now mount). What was confusing me was that all four stamps were included in the 2016 packet and 5010-11 were not in the 2015 packet.

Here's what the full panes look like, front and back:

5062-63: The images are sideways because of the width.
