Not showing availability during lunch hour

[tiffin]

I set up a scheduling link for a 75 min meeting and for some reason, it doesn't want to give options over my 12p-1pm lunch hour just on one day. My google calendar doesn't have anything booked past 11:30am and my buffer for the 75 min meeting is only 15 mins before and 15 mins after. The meeting that ends at 11:30am is a hold, so there is no buffer time. I don't understand why it isn't showing times at 12pm. I have it set to show in increments of 15 mins. This is only happening for one day. So strange!
