Usage of the word "issue"

I'm confused about the usage of the word "issue". How does it differ from "problem"?

Also, could you tell me whether this sentence correct: "There are different opinions on the issue of learning foreign languages". I feel this my guts that it's not, but I cannot be 100% sure since I'm not a native speaker.

Can I use the phrase "the issue of ____" and "the problem of ___" just with any noun?

The problem of making or buying presents
The problem of souvenirs
The issue of learning foreign languages

Thank you in advance!

'Issue' has a broader sense than 'problem' as the former means a subject or problem that people are thinking and talking about. Nevertheless, 'problem' means a thing people have to deal with or solve.

E.g. 1 - 'There are a number of issues to be discussed in the meeting. It reflects the word 'issue' refers to the topics and matters people have to discuss.

E.g. 2 'There are a number of problems for the department to address.' Then, problems means something to solve.

The issue of poverty / The problem of poverty (noun) are both correct in grammar.
