Отказ блестящей реактивности, когда на блестящей приборной панели есть два элемента табуляции

Question

Ниже приведен кодовый набор, в котором вы можете видеть, что у tabitem есть два tabitem, dash и out.Когда я заканчиваю свою панель инструментов на второй вкладке («out» или «Outlier Flagging»), используемые слайсеры не работают.Пожалуйста, помогите.
