Could you provide more details, where this occurs? Is it on CodaLab or with the provided code?

If it's Codalab, it would be nice to know which part of the benchmarks is affected, your CodaLab username, etc. Then I can have a look at the submission file. Furthermore, you can verify the submission with the validator that we provide, that does some additional checks with the submitted zip file.
