Sprint report displays flat red and green lines at sprint start.

[Anirban Paul]

We have just started our sprint today.
This problem has never happened earlier.
The sprint report shows a flat red and flat green line s per the image below.
Please help me with suggestions on how to resolve the issue.

N.B: We do have multiple boards configured under the same project and this issue is happening for the parent board

The lines indicate that there are a total of 400 hours of Remaining Time (red line) on the issues in the selected sprint and 0 hours (green line) have been logged against those issues.

Is that not an accurate representation of the state of Remaining Time and Logged Time for the issues in the selected sprint?

As per my observation for the past couple of years with JIRA I never have never observed these flat lines in the Sprint Report at the start of the sprint.
These lines start to appear as the sprint progresses and the tasks are moved and hours are burned.
I am really not sure why these are appearing at the start of the sprint.
I have not made any changes to the Estimation parameters or the Time Tracking parameters in the Board Settings.
At sprint start the Sprint Report should look similar to the image below

Please correct me if there has been some error in my observation/s
