SR not dropping survivors

Is this normal or since the 9.3 bug update.

Screenshot_20180326-181628 got this from survival road earlier today on bronze lvl stage 17 but yes no survivors.

Daily SR or Tournament? I’m getting them in tournament but I haven’t paid attention in daily.
Edit: I did daily and I am receiving them from both.

Depends on the number of waves. 1 wave no survivors.
