Look at their design and see what the difference is between their design and your design. It helps if lava and water are placed on the same height as the block breaker to prevent water or lava from flowing too fast and destroying the opposite source block. Servers tend to postpone (or even drop?) block updates if they are on heavy load, stopping water and lava from flowing.
