Because the adjective "неправильная" concern with the noun "подпись". The noun "подпись" is the word of the feminine gender therefore it must has ending of feminine gender too.
Whoops! I feel especially silly because I debated whether I should end неправильна with а or о (and obviously chose wrong). :fool" Thanks for your help!
