Redstone Piston Connecting Bug

Hello,
I have been playing MCPE on my Iphone 5S For a while now. I have noticed a bug where if you run a redstone line PAST a piston the line will connect to the piston, which extends the piston when powered. This is unlike MCPC and it messes up a lot of my redstone build ideas that I come up with on my PC. This is how to simulate it:
1. Run a redstone line of at least 2 dust on the ground.
2. Place a piston (facing any direction) On either SIDE (Not the end) Of the redstone line.
3. The redstone connects to the piston. (The Bug)
4. Power the line and the piston extends.

Please can you fix this ASAP, I respect that you have a lot of other requests and it may take a while.
I have attached an image of the bug on my Iphone 5S.

Yours,
