Contacts not syncing with iCloud because they aren’t in All iCloud List

Trying to troubleshoot why my iPhone Contacts don’t all show up on iPad and noticed they don’t show all show up in iCloud either. Following suggestions on the numerous threads here with the same problem, I checked Lists in my Contacts. All Contacts has 1402 entries but All iCloud only has 748. I assume this is the problem, but how do I get the other 648 contacts into All iCloud? Is that going to solve my problem of not seeing all Contacts on iPad? TIA
