problem with group holder YJSGMega menu
 

Hello,
I have a problem with sub menus:.
my sub menu consists of three columns, one of which is further divided into two additional columns (because it has a dozen links)
I had parametered a "group holder" with a size of 300 and two sub-groups of 150 each.
A display only the first two links are arranged in two columns. other links are one after one how can i fix this?
