Door Glitch in Chapter 6 "Support the barge along the river"

Hello there, I am stuck at this point of the game for almost 3 days and tried almost everything but nothing works. I have also updated my game to update #2 but still it doesn't work. I am stuck after I come out of the house of fire and kill the archers and then I get down. There the door should open automatically and enemies should come in by that door. But the door opens a little and all the enemies are stuck in and I cannot go in since the door doesn't open completely. Please help me to resolve this issue. I definitely liked this game and want to play this. Any help will be appreciated. Thank you in advance I have also uploaded the image with this post where I am stuck exactly.
