I am trying to set up a snippets.json file with custom codes to supplement the stock syntax, and it works, but it interferes with other Emmet syntax:

1. I made new file: snippets.json
2. Folder location: C:\Sublime Text\Data\Packages\Emmet\emmet
3. Simplified snippets.json file content: (problem occurs regardless of how many/few lines are used in snippets)
   {
   “html”: {
   “filters”: “html”,
   “profile”: “html”,
   “snippets”: {
   “d_test”: “
   test content
   ”
   }
   }
   }

So, this is successful: when I type “d_test” and press TAB it expands to:

The problem is that when the snippets.json file is present, it affects how Emmet expands its regular syntax because the results are bloated with the word “undefined”.
ie. when I type “div>div” it expands to:

Or when I type “div>ul>li” it expands to:

Is there a way to supplement Emmet with a snippets.json file without affecting the way it expands stock syntax?
