No Citrico's 8/23 or 8/24?

[Wayland10]

Hi all! I was interested in adding an ADR to Citrico's on 8/23, but when I searched I found that reservations were blocked for both 8/23 and 8/24. There is open availability on days before and after this, and it isn't saying no times are available - it looks like the restaurant itself isn't available. Is this an IT quirk, or is the restaurant closed for some reason? Any guesses?
Thanks!
