"At a glance" total user metric always displays "-" #2502

New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest versions of Parse Server and Parse Dashboard.

Issue Description

The metric at the "apps" dashboard always shows a "-" on both total users and total installations:

I have a class called "_User" per the default with one user in right now on the testing DB. I have tried to search for anyone else having this issue but could not find any. Also tried going through the source code but did not find a solution. Have I missed a config setting or is it a bug?

Steps to reproduce

This is my config. Database has the default "_User" class. On the readme the dashboard prints total users: 0

const config = {
  apps: [
    {
      serverURL: env.publicServerURL,
      appId: env.appId,
      masterKey: env.masterKey,
      readOnlyMasterKey: env.readOnlyMasterKey,
      appName: env.appName,
      supportedPushLocales: ["en"],
      production: env.DB == "prod",
      iconName: "SuitClubs.svg",
    },
  ],
  users: [
    {
      user: "master",
      pass: env.dashWritePass,
    },
    {
      user: "moderator",
      readonly: true,
      pass: env.dashReadOnlyPass,
    },
  ],
  iconsFolder: "icons",
};

Actual Outcome
