Quick answer

Slots usually vanish or wrongly appear because of free/busy calendar events, buffers, booking limits, minimum notice or slot interval. Use Availability > Launch troubleshooter to see the exact reason per time.

Most likely fix: Run the availability troubleshooter

Symptoms

Your booking page shows no times, only some times, or shows times when you are busy.

Why it happens

  • Calendar events marked Free instead of Busy (Google Calendar does this by default for some events)
  • The calendar is not toggled for conflict checking
  • Date overrides replacing normal hours
  • Buffers, booking frequency limits, minimum notice or Limit Future Bookings
  • Default on-the-hour slots hide non-standard availability like 8:15
