Forum:Missing (aka X-Ray or Silhouette) Frogs

I have been gifted several x-ray frogs that are now in my mailbox.

When they are ready to place I get a message that says, "This frog is from a newer version of Pocket Frogs.  Please update to the latest version.  Remove Item OR Continue." I press continue but never seem to be able to move them to a habitat,  Please help.
