address the problem/issue, it needs to be addressed
When you 'address' something, you pay attention to it or give it the notice and the time it deserves. You can 'address someone's concerns/problems', or 'address the issues' that need to be discussed. You will hear this used a lot in meetings when the agenda will have 'a list of issues that need to be addressed'.
