Bug Act 1 (Castlevania: Lords of Shadow)

I just started playing and then there was such a surprise ... In the first act in the second chapter, when we jump on a horse for the first time and kill the enemies. After that we jump off and we are given the task to put a block in sync with the enemy's blow. I did everything right, but then nothing happens. The task weighs and I am not allowed further. There is a solution :?
