(Clone Command) Bug

I have a World with old "clone" commandblocks and the old "clone" commandblocks works perfectly fine but when i place a new command with absouloutly the same "clone" command and i clone a shulkerbox or a chest / barrel the container closes by cloneing the block

 

the commands im working with:

Blue commandblocks (Old & New one) = testforblocks ~₁ ~₁ 982 251 1004
Green commandblocks (Old & New one) = clone ~₁ ~₁ 982 251 1004
