Duplicate Entries while using Zoho CRM API or some internal Zoho process

I am using Zoho CRM API to create Zoho Contact first and then creating Zoho Account and linking this account entry to Zoho Contact.

I found after some time Zoho CRM shows 1 contact and 2 account entries.

Is there any clue why and how its happening?
Is there some automated process in Zoho for this, so I can stop this.
