After Doing Silkscreen, Not getting Component Name , Reference Disignators and Board Outline

Hi All,

I am making the PCB of APDS-9960. After completing the process of Artwork . I went for Silk screen. I chose

Component Value: None

Device Type : None

Board Geometry: Silk

Package Geometry: Silk

Reference Designator: Silk

Tolerance: None

User Part No: None

Minimum Line length: 8.00

Element to pad clearance: 5 

then click on silk screen and saw that except that IC Reference designator there is no reference designator of other elements. And the same time there is no board outline. I don't why was this happening.

Can Somebody suggest me for this ?

Thanks in Advance
