I noticed that if I make a Sale in January but make the delivery in February, the Sales figure shows up in January while the Cost of Sales is in February.
Also if delivery is not made, the system will show the Sales revenue but the Cost of Sales will be zero.

I’ve noticed the same thing as well. I am assuming this is how the system is designed. When we issue a sales invoice from sales order, the system only books our revenue as of the posting date of the sales invoice, and when we make a Delivery Note against the same sales invoice, the system will do the necessary booking for inventory and Cost of Goods Sold as of DN posting date. So if sales invoice and delivery note are posted in different periods, there will be discrepancy like you mentioned above. But if you look at the report from January to February, for example, it should match up
