ZohoBooks Showing Estimates As Invoices in Zoho Subscriptions

Hi. We are implementing zoho subscription into our custom software. We see that "estimates" are actually showing up in zoho subscriptions as a invoice. When you click on that invoice inside of subscription is says "this invoice does not exist". The problem is a estimate shouldn't show up as a invoice ANYWHERE. Please resolve; Thanks!
