While adding two signed (2-complement) values, and they both are negative, we need to know adder's carry out bit to perform sign extending correctly. So I suggest to add carry bit input for Bit Extender in "Sign" mode. Attached circuit demonstrates current wrong behavior and how to solve the problem.
