White line showing on selected dates between Friday and saturday

[Ritvik-itech]

There is a white line showing between 16 -17 , 23 - 24 selected dates. I am not able to figure out what it is happened. I have bordered out the line showing. Please check. Thank you for this Library.

Fixed a bug related to overlapping of adjacent cells.
It was also found that white lines between cells appear only on simulators. They are absent on real devices.
