Deleted extra class name on Visual Composer

Hi! Just deleted the extra class names in visual composer column settings, because I though it was was previous plugin trial, but now the lining doesnt work anymore, and I have no idea how to make it work again. I reposted lines – nothing, I reactivated plugin – same. How do I add those elements again?

Thanks
