MS Teams Attendance - Not counting time in breakouts

Hi,

We use MS Teams regularly and we noticed there are issues in some of the downloaded attendance.

1.  We use breakouts in our calls, and Teams Attendance did not capture all attendance. (Example - Room 1 n 5 and 6 were captured but Rooms 2,3,4 were not captured)

2. We also noticed that the time attendance of some people who were in the call for the entire duration, is coming out short. (Example - 1 hour instead of 1 hr and 30 mins)

What can we do to manage this attendance issues?
We are the main organizer of the call and we manage the breakout rooms. 

Thank you
