Why doesn't the burnup report in next-gen project reflect the modified sprint scope?

[Michał Kamiński]

During the sprint, I removed the story point estimate from a couple of tickets. 

This was not reflected on the burnup report, it still shows the old higher scope. 

When I remove the actual ticket from the sprint, the report reflects that. 

Is that a bug?

[Peter Forsythe]

I've removed two cases from the sprint, received a message that scope will be affected.  On checking the burn-up and burn-down reports I can see nothing related to the removed cases.  They don't appear under "Issues removed from sprint" nor have their estimates been removed. This means the scope was not updated.  Anybody else seeing this?
