Issue on sync record smart service for service backed record type.

I created a service backed record type with sharepoint list as data source.

The record type is sync enabled.

New list is created or updated frequently from sharepoint list on a day.

So daily sync is not enough.

The client wants to have an option like a button to trigger sync right away.

So far, I already configure sync option for the record type.

And created a process model to trigger the sync

The issue is only the records available in my record type gets sync on updates.

But the record I newly created in sharepoint list dont get sync in my record type.

Appreciate the help you could extend to me. Thanks
