Bug in CS50's score counting?

Question

I checked my "CS50.me:Scores" recently, and was surprised to find that the score of my first two programs that I submitted in 2017 changed from 100% to 75%! I understand that they introduced a new criteria called style, but how can I get 0 out of 5 for style in programs as simple as Hello and Mario(less) and 5/5 in the rest?! (considering the style in which I code is unchanged)

Here is the code for Hello that I submitted and got 0/5 for its style:

#include <cs50.h>
#include <stdio.h>

int main(void)
{   
    //Displaying desired output
    printf("hello, world\n");
}

And here is the proof of whatever I am complaining about is absolutely true! :

Please tell me whether I actually deserve 0/5 for its style or it is a bug, in which case please fix it at the earliest, it is unfair to decrease my score in this manner!

Answer 1

If you need to submit your code to fix the style, be sure to run style50 and then use the 2018 submission instructions.

submit50 cs50/2018/x/hello

submit50 cs50/2018/x/mario/less
