Is lid not part of Resmed H4i humidifier reservoir?

I ordered a replacement water reservoir for my Resmed 8 Autoset Vantage, because after about a year, it leaks and my numbers get bad.
But they only sent the bottom part. Are lids not considered part of the replacement? Its probably the lid that leaks more than the bottom.
Thanks.

As in the diagram you should have also bought the Top Cover and Seal(26953) Hope this helps

The last time I ordered one, I got the lid with it. It was an upgrade from the 3hi, so maybe it was all included because of that. But it was still just the price of the bottom that I'm paying for now. But dang, I wish they'd asked me if I needed a lid too. Its more the lid that leaks. Now I can't order it for 4 days because of the holiday on monday, which means more time with big leaks.
