i5Grid issue

Hi,

I configured Display Template with i5Grid of Grid Type Lights.

In the Layout category I assigned 11 columns. I defined 1st column width 50 and the remaining 10 columns width 0 as I want to hide those 10 columns in the display.

when I test the display template, the display comes like as shown in the attached screen.There is some black lines coming around lights.

If I try to expand the black lines, the hided columns are displayed.

Is there any settings that I missed to eliminate the black lines around the lights.

Regards,

Naga.
