Order Number Add an extra digit Sometimes / POS PRO

[DavidSanchez]

Hello Friends from Shopify.

I'm asking for help. I can't figure it out why my order numbers add an extra "2-" on some orders.

We do have only one location.
We only have one salesman per shift.

What could be generating this change of order number?

The prefix and suffix config here

Any advice is welcome.

Best Regards.
