Redirecting in editing task board

When I edit task on SHORTEN it redirects me to... SHORTEN (after modifying it).
BUT when I edit TESTS in the same task in redirects me to... main SPOJ.
I find it quite annoying because I'm such kind of person who edit task (and programs) lots of times (instead of making a good one at the beginning) and I have to go from main SPOJ back to SHORTEN again and again.
Example:
https://www.spoj.pl/SHORTEN/problems/BINCLOCK/edit/complete/ (that's where it takes me after editing description of a task and saving it)
https://www.spoj.pl/problems/BINCLOCK/edit/ (and that's where it takes me after adding a test to the same task)

Edit (as I said ): It happens not exactly after adding tests but after clicking "Update" button.
