Rifleman, old boy, the word "issue" has many meanings.
In no particular order, it can mean an utterence of a periodical, the fruit of one's loins, the fruit of a collective people's loins, a point of contention, a talking point, as well as more arcane uses.
This is certainly not the first time you have heard words that have many meanings. Even a dictionary for children will contain more than one meaning for a given word where appropriate.
You may chose to use only the one meaning, but don't be surprised if learned people go ahead with other applications.
