Why does Zoho Invoice double count invoice activities

I'm new to Zoho Invoice and I like what it does and how it works.

But it seems your pricing model charges for multiple invoice activities on the same invoice.

For example, If I draft an invoice that gets counted as an invoice raised. If I save it or make it open, that's another invoice "raised". If I post it, that's _another_ invoice raised.

In practice, there's _one_ invoice and three raisings.

Is that correct? If so Zoho should come clean on the basis of its fees.

If not, please advise best practice as I've just run out of invoices for my client due to this novel accounting.
