A dot after an attendee's name, such as Hannah ., means HeySummit could not derive a last name when registering that attendee with Zoom. HeySummit splits the attendee's full name at spaces, sends the first part as the first name and the remaining parts as the last name. If there is no last-name part, it sends a dot as a placeholder.
Collect the names you need
Go to Event Settings > Event Experience > Registration & Checkout Settings and review Attendee Last Name. It can be required, optional or hidden. Requiring it helps collect last names for new registrations.
Review imported and manually entered attendee names too. A single-word name can still produce the dot placeholder.
For existing attendees, correct the name before a future Zoom registration. Changing a label does not retroactively change attendee data or an existing Zoom registrant.
Clarify the registration wording
Go to Event Settings > Content Translations and search for the first-name and last-name prompts. Use clear wording so attendees know what to enter. Translations change the wording; they do not make an optional or hidden field required.
