Footprint of Si1143 Gesture Control

Hi All,

I was making the footprint of Si114x Sensor. As the dimensions are given in the datasheet 

I chose the pad dimensions

Width=12 mils

Height = 16 mils

For making footprint

The package type is 10-QFN, So I chose PLLC/QFP package

Vertical pin count=4

Horizontal Pin count=1

Lead Pitch=20 mils

e1=95

e2 =95

D=79

E=79

then it is showing 6 DRC error.

I don't know, what mistake  that i am doing.

please see the datasheet

Can somebody suggest me how to resolve this problem?

Thanks in advance.
