client carousel double stacked

Hi,

Trying to instal client carousel but it shows as double stacked. I have 15 items total. I tried about everything and nothing works. please help.

Something like this below, where just one of the clients shows on second row. Please help. Sometimes by resizing the page it shows the way it should but as resizing continues a second row comes up.
