Why do some reservation times show up, but are grayed out?

[Goofy4]

Sanaa has a couple grayed out times. I was hoping that it could be a sign that they will open up, but no luck thus far.

Having now read https://www.disboards.com/threads/grayed-out-reservation-times.3943857/ I still can't make sense of it. It doesn't appear to be "party size".

Anyone have additional insight since that thread?

In case it helps, I will answer my own question with this from TP:

Depending on exactly what you searched, you may see some greyed-out times. These don’t mean that if you select a different-sized party those times will become available. Instead, they mark the endpoints of the meal period and the beginning of any hours within the meal period.
