React-native-calendars: onDayPress not highlighting day?

[Oakyden]

I have simply placed calendar in one of my app screens:

onDayPress={(day) => {
console.log('selected day', day);

      }}
       />

Expected Behavior

I thought a pressed day would highlight with blue by default as seen in the GIF screenshots

Observed Behavior

Console log is working, so onDayPress is definitely registering, but the pressed day does not highlight.
