Why I create the same as project?

I have using the create project button by “manually” option, but when I created the new project, I found them have same name? like this:

only they have different pjoectkey
and why I have exclusions some folders, but they have scan always?

sonarqube version is developer edition 9.3


When you create a project manually, there’s a little form to fill out where you supply name and key. And then at each analysis you have the opportunity to rename a project just by passing a new sonar.projectName value. Perhaps some CI-side automation has a hard-coded value where there should be a variable?
