Unable to change existing schedules

[lrupp]

I'm using g9542f7 here on Firefox/Linux and have created 2 schedules via templates for a team with one roster.

While my account is marked as "god" in the user table (which IMHO makes me admin), I can not change a schedule (in the future) created by the "Populate Schedule".

What I found out is that the tool already checks if a user is available for the given schedule (very nice) if I want to swap shift, so a user on vacation can not be chosen.

But what I expect is that I could - for example - change the hour or even day of the existing schedule, or even delete this schedule completely. This does not work for me. The popup window with the details open and I see the "Delete", "Save" and "Cancel" buttons - but everything I do/click in this window does not work. The buttons have no effect.
