Grade for submission - wrong aspects calculations

It seem to be a bug when updating Assertion weights during evaluation phase, after grades already given.

We use 5 assertions with weights
Students start submit >  then continue to the "assessment phase" >  and assess their friend > then continue to the "grading evaluation phase" > the grades look fine in the "Grades given" column.

Now , the teacher wants to change the weights of some assertions (for example some assertions to 0 weight some to 1) -> saving -> coming back to the on "grading evaluation phase" -> we see wrong calculation in the "grades given" column (the old calculation before the aspect changes)  and not the new calculations that we were expecting.

There is no way to recalculate the "grades given" from the aspects, after a change (like the above).

Can you make sure it's not a bug?
Is there a way to recalculate the "grades given" after changing assertions and also after the submissions and assesses were done?

Thank you
