Recurring Invoices been generated twice

I am having issues with Recurring invoices been generated twice for every time. See details below.

I Created a Recurring invoice on Oct/1 with daily frequency, when I set it to start, I got a email sent. than on Oct/02, it ran but sent two. it was supposed to send only one per day.
Also you can see even it have generated 3 invoices and sent in two days, it still showing 3 remaining cycles.


Is this happening with all invoices or just some?

Is it possible you have more than one recurring invoice or an extra cron?

Let me check for duplicated Cron,

I did found double cron fotr this domain, I fixed, will run new set of recurring invoices to see how it react now, thank you.
