Same issue. In multiplayer my friend is seeing the correct block, but on my end placing dirt and stone is showing as one or two pistons. Opening a door will turn it into buttons. Using a button will turn it to stairs. Rail turned into quartz❓ . Just tapping a block w/o a tool will turn it. Work tables are unusable as they turn to random blocks. Breaking the unwanted blocks, they don't pick up and get added to inventory.
