Breadcrumb did not reset on calendar and dashboards Apps

Breadcrumb did not reset on calendar and dashboards Apps.

1st POINT (bug ?) when Breadcrumb is activated either in menu nor in Tmenu, the breadcrumb did not reset on Calendars apps neither on Dashboards apps.
you may see this buggy feature in video screen capture here Dropbox Capture

As you see, I test it on a minimal and “pure” SC project, all automatic

How did you manage breadcrumbs ion your projects ? SC seems buggy

Thanks in Advance,
