As Laurel has noted in comments, this is how the system notifies you that someone else considers there is already an answer to your question.
You get such a notification every time someone casts a vote to that effect, and that is by design.
It is your opportunity to examine the offered answer(s) and either say
- Yes, I can apply that to my question¹
- No, it doesn't apply to my question, because... and then update your question to explain how it is not helped.
Every time you get a "Does this answer your question?" notification and you answer No, you should edit your question to explain how your question is different. You need to show that your question is not answered elsewhere.
¹ Very often, a "duplicate" is not exactly the same question [those are merged] but one where the answer or its explanation can be applied to your question. A question about "The government is/are" would be answered by a question about "The police is/are" or "The team is/are". If you cannot apply the thinking behind the suggested answers to your question, you need to explain why it doesn't apply in your case.
