Question

Блок отображается в верхней части верхнего блока при первой загрузке и фиксируется при обновлении страницы. В мобильной версии сайта такая же ситуация. Иногда отображается правильно. Сам сайт подключен к WordPress, оптимизирован с помощью ниндзя Page Speed. Изменены настройки ниндзя Page Speed, пока безрезультатно. Как я могу это исправить?

Экран мобильной версии, когда сайт открыт

Экран мобильной версии, после обновления
