Showing 0 score when submitted after getting all correct test cases

I did submit the code for the first time and did not get any response and then after submitting the same code again I got all correct and even after that its showing the score as 0.why?

@Mohit_Maroo after submitting for the first time, did you unlock editorial or downloaded the test cases?

No, I did not unlock editorial.

There was a technical issue. Try submitting it now.
