Galaxy S7 only partially syncs contacts from Google account

[dry_erase]

Hello,

I've just got a Galaxy S7, and want to install my contacts from my Google account, where they are all backed up. But for some reason, only some of the contacts are syncing to my phone when I activate the sync as directed.

I've followed instructions to go:

Settings > accounts > Google > sync contacts > "SWITCH "ON"

...but the upshot is all I get is the partial sync - 34 contacts randomly from hundreds! Any ideas?

Thanks!
