You could see the touch of each Weasley in the house. It’s visible in the ward system too. Different methodologies being applied to the system. While I could understand the possibility of that reinforcing the system, instead it actually made it weaker. There were conflicting layers that prevented parts of the system to work. I had originally thought about reinforcing the wards, but I’m sure that if I made any modifications to it, it would fail tremendously. It would be better if I just alert Mr. Weasley about it and hope that they deal with it properly.
