My Leave Request Fiori App - Errors with the screen

Hi

I set up the My Leave Request App, found the following errors

1) absense types dropdown is empty

2) There is no FROM & TO date fields on the screen

3) Used & Available vacations do not get displayed

4) Calender - The calender only allow to select a single date? Why is not multi-select or Range..Is there a config where I can change the selection mode of the calender

Here is a screenshot of the problems

Thanks
