Block connected to honey is duplicated when the honey is being pushed by pistons repeatibly

What I expected to happen was...:

I expected the block to be pushed around.

What actually happened was...:

What actually happened was that the block was duplicated

4. Place a honey block between the two pistons

5. Place any movable block on top of the honey block
