We appreciate you clarifying this for us, CMon17,
If you sign into your Google account via a web browser, are you able to see the complete contact information there?
Do you have Google set as your Default Account in Settings > Contacts > Default Account?
This is also a handy resource to help you to manage your Contacts: Manage and delete contacts on your iPhone or iPad - Apple Support
"Choose a default account to add new contacts
If you set up multiple accounts in the Contacts app, you can choose a default account to add new contacts to:
- Go to Settings > Contacts > Default Account.
- Choose an account."
If you're seeing that contact information is missing when you sign into your account via a web browser, you may consider contacting Google directly to take a look at your account with you.
We hope this helps.
Cheers!
