Smoking and other hobbies glitch

On Xbox 1 X. I’m trying to finish everything I possibly can in the game but I can’t mail the Gems of Beauty card set. I completed the set before the credits rolled and was able to mail them all in but the box didn’t check for the Gems set. After the credits rolled, I bought enough premium cigarettes to get another complete Gems set and went back to the local post office. It allowed me to mail in some sets I had completed again from my cigarette shopping spree, BUT not the Gems set! Now I have at least two of every card in the Gems set but I don’t have the option to send any mail. There’s lots of little bugs in the game that I’m willing to overlook because of how awesome it is, but this one is super frustrating.
