Check that in your submissions weeks 50 and 51 are not all zeros. These weeks fall within the active prediction horizon, so they should have meaningful predicted values rather than zeros.
it made all my scores from beginning to now are the same,even when i submit with the new prediction of week 51 , it's making my score the same as the previous one, so now all of my scores are the same number.
