Tasks in weekly view: is it bug or not?

Hi guys!
Please help me understand, is this tasks view in Calendar with weeks view as it should look like? They look the same in the day view - just a line with calendar’s color, nothing else.

Or the tasks should look the same is in the month view - see below:

In this view tasks have a bit additional information like endtime + names.
So, is it a bug with week view?
