Tag beats URL

When adding a listing it seems if I put the title, for example Hempé, and while creating the listing I add the tag Hempé when all is published the tag beats the listing url to the punch creating a url with “-1” for the listing. I feel like the listing urls are more important than the tag urls. The listing url is part of what someone is paying for when they list, at least I think it is, hence the term “pretty url”, everyone prefers one. Is there a way to prevent tags beating the URL?
