'Unable to resolve duplicate header in Docusaurus MD File

I dont understand why two headers are coming on my MD pages. I dont want "intro" header written. also, in my sidebar, the pages are fetching the md file name rather than its name. I have added the Introduction page md file starting snippet. PS: I am using standard sidebar and not the custom one.
