Item frames gone/invisible.

Hello i was trying to record a video about crafting.
So, i maded a house with Item frames in (So it's looks like a crafting tabel)
And putted my items in there i was making a bone block !
So once i maded my bone block i goes to my build area (with a command block tp
So in the build area there is also a command block to tp back to the crafting house with the item frames, and once is goes in my crafting house the item frames are just gone. It was only wood block so i thought let's break that wood bloks and place the item frames again, and once i broked 1 wood block it's drops the wood block + the item frame so yeh.
The items frames are just invisible.. :/ Fix that bug pls !
