Conceding penalties on defence

So this is annoying the living daylights out of me.. now all of a sudden my games look like this.. my 10 kicks off.. they catch the ball run it to half way then my player tackles.. just there and then i concede a penalty... this can continue whole game.. i dont know what im doing wrong.. i dropped all aggresion but still this happens

The morale of your players is set far too low, it affects performance. Raise the morale and you should see an improvement, all round. Mine is set at 99%, to give you an indication.
