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
