Success score

[az_design1]

Hi everyone, My success score is way too low and it is because 3 people spammed me, they ordered from my gig and canceled it one minute later before even completing the requirement section, Fiverr, of course, notified me that it has no impact on your gig's visibility but now I see a strong negative impact on my gig's success score due to cancelation, other than these 3 spams I have no cancelations on my gig, 2 questions: 1st: if Fiverr says it has no impact on your gig then why does my gig's success score show it? 2nd: if the success score is an overall score, how am I supposed to improve it with the few orders I will get? If I do them perfectly with perfect private and public reviews, they aren't changing anything, are they?
Thanks for your time!
