I updated the JSON file to point to some new CSS content, now "Paragraph Styles" no longer appears in the text editor. What could have caused this?

JSON:

{
  "version-info": {
    "author": "Brad Marshall",
    "updated": "02/08/2019"
  },
  "paragraphStyles": {
    "study-callout": "Study Callout",
    "study-callout study-callout-heading": "Study Callout Heading",
    "study-callout study-callout-close": "Study Callout Closing",
    "accordion": "Accordion Header",
    "panel": "Accordion Panel",
    "tooltip": "Tooltip",
    "tooltiptext" "Tooltip Text"
  }
}
