what is the difference between Issue and problem?

Anything that matters is an issue. You may know the solution even before the issue arises. An issue is a small matter. A problem is a big matter. Forgetting to take lunch box to your office is an issue. But losing job is a problem.

When we talk of social issue, we mean all topic that matter to the society. But when we do not get any answer to an issue easily and this is very urgent, this becomes a problem.

See link below for better appreciation of difference between 'issue' and 'problem'.

Issue is a matter which can be solved, a problem is a matter which needs to be solved and where we don't know if it is wrong or right

The act of circulating, distributing by anoffice is called as an issue.
A problem is an obstacle, that invites any resolution.
