Spoiler Goddess Cube/treasure #10 Problems

[RedDekuScrub]

Ok, so I was playing Skyward Sword and I got to Lanayru mines. Behind the entrance point (when you come from the sky) you see Goddess cube number 10. I hit it, go to the sky and I CAN'T FIND THE TREASURE. It doesn't appear on my map. I also checked various guides and went to the point where the treasure is supposed to activate and it's not activated it. Could someone please tell me if there is a way to fix this? Where is the exact location of the treasure? Please help me! Thank you!

This would be a wild guess but, then there is a high possibilty that the chest is located in Skyloft. Go to Skyloft and check the map.

It's most likely located in either Skyloft or the Thunderhead.
