"Open, but no spaces today"

I tried to register today around the time my registration period opened but when I register for a couple of my classes it says, “Open, but no spaces today”. I checked the time schedule and it still shows open spots but the classes are apparently closed for the day. Can I get a explanation on why this is?

Thanks.
