So I was looking at the play calls for this last game and I noticed that a play was called that is not in my play sheet and it resulted in an interception. I clicked on the play and it says its in my playbook but I can't find it. Is this a glitch or has this happened to any body else before.

Not that I've noticed

make sure the "minimum times called" is set to 1 and and everything else is set to include all plays in all personnel groupings.
