We got 2 weird issues in the display of the jobs in the monitor:
First: one of the job is showing 4 active slave but there isn’t any task rendering(plus the color isn’t the correct one).
Second: one of the job suddenly duplicated itself and was queued with the exact time, it happened twice.

How are you confirming this? The screen shot doesn’t show the tasks for the job, so we can’t see what the tasks are doing. Also, the color is Green, which is correct for an active job.
That’s weird… do you know if the duplication occurred right when the job was submitted, or did it occur later? Also, can you check the Job ID column for the duplicate jobs? If they match, it could just be a display issue. If they do match, try restarting the Monitor to see if that removes the duplicate.
Actually, that might explain the problem of the other job showing that it is rendering when it’s not. It could be an old ghost of the other job. So yeah, definitely check the Job ID column to see if they match, and let us know if restarting the Monitor gets rid of the duplicate.
After closing and reopening the deadline monitor it was fixed, but still that’s weird.
The green color that shows in the attached picture is a different green from the active one.
That’s good. 
We’ve logged it as a bug, but since it’s just a display issue, it should be much easier to track down.
When errors occur for a job, we blend the color with a light red color so that it’s clear when jobs are generating errors.
It looks like we’ve found a solution to the duplicate job bug. It will be included in beta 9.
