Orders sometime have a second invoice on them for zero amount.

[traknet]

Hi, Using Magento 2.3.5 (Luma) most of the time when an order is put on there is just one invoice for the full amount which is how it should work and is fine. Occasionally and order has a second invoice on it for zero amount. Has anyone come across this or know why it could happen?

Thanks

Hi @traknet 

It can happen only in one case if you are using observer for create invoice on below events:
1. sales_order_save_after

2. checkout_submit_all_after

Please confirm with you Magento2 modules, is there any observer has been created with any module.

Hi, I'm not very experienced in Magento so don't really understand what I'm looking for here.

How do I check what you say?

Thanks
