Contact Syncing Limited to 50

Upgraded from an older version of this container 3.5.0.1 to the latest 3.5.6.0, we had hundreds of contacts and now when disabling and re-enabling contact syncing on iPhone, only 50 contacts are syncing. I reverted back to 3.5.0.1 and then performed the same steps, deactivate the dav contact list, re-activate and all hundred+ contacts came back. I found this step wasn't even really required as other devices would have their contact list jump up from 50 to the hundred+ contacts automatically. The issue seems to be with either the latest version, or from some version in-between.
