Hi! Valarie. Let me help you with this.
Please check the Calendar Visibility.
Make sure the blank calendar is actually checked in the left-hand list under "My Calendars" or "Other calendars" on the web version of Google Calendar, unchecked calendars appear blank. Try unchecking and rechecking it to force a refresh.
On mobile, verify the calendar is enabled and syncing in the app settings.
Best regards,
Kimberly
