Missing some orders when retrieving all orders by API

[Jen2021_SS]

Hi, when I tried to retrieve specific order, I found that some of the orders were missing with or without any params, e.g. limit, name, financial_status, etc. I can find the order created today and others from yesterday or even eariler. 

Can anyone help me please? Thank you.

Here is one of the example:
