I'm using April Dunnham's date picker component (https://github.com/aprildunnam/PowerApps/blob/master/Components/Calendar%20Component%20(4).msapp)
I would like to pass date values to this component. The date values are in a sharepoint list:

Inside the component, I set a sample table for the CalendarItems input property to:
Table({Title: "Meeting sample ",Start: "6/12/2021 1:00 PM"})
and I have a gallery inside the component with Items set to CalendarComponent.CalendarItems. This shows up as expected when I'm in the component layout, and If I'm in my screen where this component is used:

The problem is when I get the Title and Start from my sharepoint list, the date doesn't show up correctly:

Any idea what is going on here? As you can see, the title displays correctly, while the Start field contains a13-digit number.
