Guess it's a problem from the competition itself because I'm also getting it.

Same for me

Am also experiencing the same problem.

We are looking in to this. Thank you SO much for your patience.

I made a mistake with the reference file and used a lower case "t" for "Target".

You were right to use the capital "T".

You don't need to resubmit your files (unless you want to) as the rescore will happen this week and you will be able to see your scores.
