tp.system.suggester shows label for first option when multiple options have the same value

[Zih-Ying]

Plugin information (please complete the following information):

• OS: Windows 10
• Templater version: 2.18.1
• Obsidian version: 1.12.7
• Templater settings: Template folder location: "/_templater"

Describe the bug
Every separator displays the same label as the first one, regardless of its actual value.

Expected behavior
Each separator should display its own correct label (e.g. ── Grid ──, ── Standard ──).

Screenshots
I verified the displayList array in the console and confirmed the values are correct

Additional context
Code below.

<%*
selection = tp.file.selection()

const groups = [
  {
    label: '── Grid ──',
    items: {
      'grid|col-2': ' ƒ  grid (2 column in default, option: 3, 4)',
      'grid|25%': ' ƒ  two non-even column grid (25% column in default, option: 33%, 75%)',
    }
  },
  {
    label: '── Standard ──',
    items: {
      Note: '🟦 Note',
      Info: '🟦 Info',
      Todo: '🟦 Todo',
      Summary: '💧 Summary/Abstract',
      Tip: '💧 Tip/Hint/Important',
      Check: '🟩 Success, Check, Done',
      FAQ: '🟧 Question, Help, FAQ',
      Caution: '🟧 Caution, Attention',
      Fail: '🟥 Failure, Fail, Missing',
      Danger: '🟥 Danger',
      Bug: '🟥 Bug',
      Example: '🟪 Example',
      Cite: '⬛ Quote, Cite',
    }
  },
]

let num = 0; //number of all callouts
const displayList = []
const valueList = []

// Flatten
for (const group of groups) { //change to let not affect result
  displayList.push(group.label)
  valueList.push(null)
  for (const [key, desc] of Object.entries(group.items)) { //converts an object into an array of `[key, value]` pairs
    displayList.push(desc);
    valueList.push(key);
    num++;
  }
}
console.log(displayList)
let type = null
while (!type) {
  type = await tp.system.suggester(displayList, valueList, true, 'Select callout type. (' + num + ' options)')
}

if (type.includes("grid")) {
  return ">[!" + type + "]\n>>\n>\n>>"
} else {
  return ">[!" + type + "]\n>"
}
-%>

That's because you have two items with the same value of null.

I recommend using a different technique so Templater can differentiate between your groups.
