Another PigLatin test failure question

Question

Good day! Could someone please explain why the first version of the code from the example passes all the checks of the code_coach PigLatin, despite the presence of an extra space at the end of the output line, and the second code does not pass the 3rd and 5th checks. Thanks.

Answer 1

Try input: xxxxn yyyyn
It has something to do with the fact that if first letter is repeating inside the word.
EDIT:
Found example with actual word:
successful
your ouput: uccefulsay
expected: uccessfulsay
