Fundamentals of Accelerated Computing with CUDA Python. Failed status on a passed assessment

I went back to an assessment (Introduction to CUDA with Numba) I had passed to review and presses assess task instead of stop and now it marks it as failed. Also the assessment following(Custom CUDA Kernels in Python with Numba) does not give me feedback to what may be wrong with my code. Instead it only says error try again but my code and output seem to be correct.
