filtering aliexpress orders - a mess

Not alidropship related, but im really having difficulties with aliexpress order filters.

I want to filter orders by date. For example 1september to 30th september. But 30th september orders are not there. I dont understand why it does not filter properly. Anyone else has same issues?
Also, when I search just 1 day. Like 30th september to 30th september, it cannot find any orders.. But it can find 30th september orders when I search 1st september to 1st october... -.- I need invoices for bookeeping and this just .... yeah
