I can confirm I have the same issue on iOS.
react-native 0.61.5, react-native-calendars 1.220.0

Other issues related to the header:

1. Header has 2 week day rows like shown picture above but without opening the knob.
2. Header does not navigate correctly to the selected day, showing a random week.
