I just took a MT job by accident and already invested some work before noticing that the volume didn't match the reward.
I remember coming across one of these before and the actual (in my opinion too low) rate was displayed, so not sure if this is a bug or an intentional change.
Granted I should have paid more attention to the volume, but I do feel kind of tricked.
Other than the matches displaying MT (if they are opened, which I don't think was the case here initially, and come to think of it, the other MT job I came across had the MT already filled in, which wasn't the case here either) and the volume, rate and reward not matching up, there is no indication this is a post editing job (actually TM for translation memory is displayed at the top). I'd prefer a clear and easy to see distinction like with edit jobs and at the very least the correct rate.
I dimly recall there might have been some announcements regarding this a while back, but still some clear visual pointers are needed in my opinion.
Will pass this on to support as well, along with a screenshot, but I figured this is an issue that concerns all translators, so be careful to check if the displayed rate is correct before you start.
Additionally, it would make sense for the light bulb symbol to indicate if suggestions are present. Currently it's grayed out either way. Not sure if that's the intended behavior.
