Bookings is not showing any availability on calendar

Hello All,

I am having an issue where one of my users can no longer any availability on My bookings calendar. He has the Book with Me link in his signature. When potential customers click on the link, my bookings page shows no availability to the customer. When he looks at his calendar in Outlook it shows he has availability. He is using the default my bookings configuration (did not create his own). I am unable to replicate it on my end. We are using M365 Standard as well.  Can someone help with this?
