What’s the deal with the prompts

Why is it when I make a prompt I will always press the regenerate button so that Suno words it in its own ways and it sometimes throws out some good stuff but after maybe 3 creates with the same prompt I can’t make anymore. It will have a pop up that says that the prompt it’s under moderation like something that would happen if it was against community guidelines but it’s sunos own prompt in theory so what the problem, anyone else had this problem
