Пропадают всплывающие подсказки Chart.js

Столкнулся с такой проблемой. Есть 2 графика на Chart js, 1 из них линейный с ним всё в порядке, 2-й столбчатый у обоих графиков ось X типом time. Стобчатый график stacked:true. Проблема в том что если у столбчатого графика стоит тип оси время то всплывающие подсказки на нём не отображаются. Если стоит любой другой тип то всё хорошо. В чём может быть проблема и какие пути решения.
