Legend of Zelda TP question?

Ok i have already beten the game already b4, but i decided to do a re-run, you know to get the poes, bugs, etc. And you know when you are in the hidden village and you have to kill all of the goblin things, and they fall off the railings, and break a part of the rail. Well i did that, and i came back later to get a poe that was there ( 1 of the last poes!) and you have to clawshot one of the nets that is up there to reach the poe. so i got out my clawshot, looked up, and the railing was back! So i tried to clawshot up anywhy, but of course, it didn't work. Link wouldn't climb up all the way, past the rail. So i really worked hard to break the rail, but nothing worked. And i spend almost 3 hours to get all of the previous poes, and i don't want to give up because of this stupid one. so plz someone help!
