Hello allenumali,
Thanks for that info. Since it's only that one card so far, see if you have multiple Contacts account.
If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support
"If your contacts, calendars, and reminders are in iCloud, then iCloud automatically updates your information. If your information is in a third-party account, like Google or Yahoo, you can change your default account to iCloud. Changing your default account to iCloud won't move your existing information from a third-party service to iCloud."
It's possible her card is coming from some other place, such as your email, where these changes may not stick.
If it's not that, then please contact us using this link so we can investigate further with you: Apple Support
Thanks.
