I am also experiencing this issue. It's very annoying.

I got the same issue too. Hope it is fixed soon

For me the titles are duplicated always. No matter if there is content after title.

I've found this happens when there's a space between the "#" symbol and the header, for example:

"info": {
    "title": "",
    "description": "# Test",
    "version": ""
},

 It can be temporarily fixed by removing the space:
     "info": {
        "title": "",
        "description": "#Test",
        "version": ""
},
 Markdown standard has a space between so this must be some sort of issue with how the markdown is being generated from the json.
