WP Hummingbird - penalises itself.. and Pagespeed isn't a fan either..

Installed Wp Hummingbird a little while back to test it out, and sure it does nice things but what leaves me somewhat baffled is why when running its own test it will penalised itself for render block resources and minification faliures. I Have no other issues (optimized everything else) and so the plaugins scripts and inability to minify its own CSS file are the only thing really keeping me from getting 100% score on its own test AND more importantly on Pagespeed test. Why exactly can't hummingbrid scripts be positioned to the footer, why arent they avaible in the listings? Heck why does a plugin designed for speed cause the very things its trying to fix?
