How to resolve "Reinforce bar is not exist" Error in SRC Column Design?


I have defined a simple column which defines by SRC material. I checked Material Properties, Load Combination, and others, they are OK. However, when I check the design in SRC Design, it appears " Reinforce bar is not exist" How to resolve this?

Kindly refer to the message window.  The error message is highlighted in the image below.

Since the spacing is not sufficient to put the re-bar, the design isn't being performed.  
Kindly increase the section size and retry.
