Stunning issue

So i just faught a cygness that used Water Torrent and was stunned. My following attack was Rock fall and it stunned cygness. But it showed a second stunn symbol and both marked With 1. so both stunn symbols vanished in the Same round.

This does not make sense. It shouldve been stunned for another round. That way stunning was for nothing .

This needs to be fixed. If there is 2 stunning caused then there should be 2.

Happen to me LOTS of times..
I already post it on bug section and support says they gonna test it..
