EDIT: I understand this was not clear when i originally posted but these screenshots are from the dates I originally attempted to book and was unable to, not today. The standard rate rooms are no longer available for these dates.
I was purposefully cagey regarding the dates and hotel originally because I didn't want it to sell out but I did take some screenshots and you can see both standard room availability (sorry its a bit cut off) as well as no points availability.
No points available but standard room availability
Chat rep confirming this is the case and it's ok
