отображение только двух карточек из трех на моей панели

Question

Я создаю панель мониторинга для своей CRM. Однако при отображении вида карточек видны только два из трех представлений карточек. Может ли кто-нибудь помочь мне в этом? Это проблема форматирования кода?

Я добавляю изображение панели инструментов для моей CRM ниже, а также код для карт, приведенных ниже.
