Когда я нажимаю на вкладку, она показывает содержимое вкладки, но если я нажимаю на нее во второй раз, это не так. Вы можете увидеть это в действии на bootply:
https://www.bootply.com/4gEG55Wgr4
Я попробовал совет, предложенный на Bootstrap 4 - выпадающие списки работают только один раз с меню вкладок , но это не имело никакого значения.
Любой совет будет принят с благодарностью,
Тим
