The first row of the calendar(date picker) is overlapping with the second row

I am using a date picker in one of my forms and the dates in the first and second row are not rendering properly i.e. they are overlapping. Its not just at one place but its happening everywhere i am using the date picker view.

It can be viewed at this link: Capture — ImgBB
