A couple of comments. Not sure if the queries have to use the old commission names (probably do). Just as long as those don't appear in the GUI. That was probably in a different PR.

When commission is 0% the display in the overview and details is weird:

And when I change commission to 0%, the indicator/changes doesn't appear.

Had wrong condition check which captured 0. Replaced with check on undefined and null and validated it correctly renders 0 and the indicator.
