Issues with progressbars while adding courses

[Remolos]

When I have an empty POM module everything looks fine. But if I add a POM seminar, this progress bar seems to correctly indicate it as a compulsory curse, but the numbers label change indicating that there are still 10 credits missing in the compulsory module, while the bar is corresponding to the correct 4 credits(at least I think it does). Furthermore the optional compulsory bar corresponds to 8 missing credits, but the number label say their are two missing.
When I add the grade of the course everything is fine again.
There is sometimes an issue where the missing credits in the optional compulsory module are displayed as negative numbers, but I can't reproduce it.
