Short answer: I don't know.
Long answer: Were your references as good as the rest of your application?

Who is writing your reference letters? Is it some prof who is very busy and would just write you a lousy reference letter? Or is it some prof who never really liked you to start with?
Here are some details to guide you;
1. The name of the scholarship/program you're applying to.
2. The addressee
3. Mode of submission...
5. Specific information that you have probably mentioned in your essays that your referee can corroborate.
6. Other things you engaged in as a student that your prof wasn't fully aware of (extracurricular activities, clubs, leadership positions).
8. Don't ask them for reference at the last minute (except if it is an opportunity you saw at the last minute). You should have at least one...
Send them a reminder every couple of weeks or when it is a few weeks to the deadline to see if they will still be able to send in the reference letter for you.
You need them to be able to speak positively about you, vouch for you as it were not just lukewarm.
All the best in your next application(s).
I still can't believe what some of them wrote for me, imagine reading your own reference letter and asking yourself "is that me?" And those who would even write me a reference letter in two days, may God continue to bless them too.
You don't have to give them money (even though they deserve it and you should give if you have), but staying in touch makes them happy.
