Had same issue. I stumbled onto my missing plays hidden in the wrong set during game play.
Instead of being included with the formation sets where I saved them, my missing plays were under the Hail Mary set. Weird but I had reloaded twice and was pissed they only showed up under coaching suggestions.
Click like you would for a HM then scroll right or left. They may be there.

This is happening to me too. Very annoying getting into a online head to head game and not having any shotgun plays lol
