`leaderboard_decimal_precision` and `is_leaderboard_order_descending` cannot be set from `challenge_config.yaml`

I've been testing a challenge on an local EvalAI clone but have been unable to properly set `leaderboard_decimal_precision` and `is_leaderboard_order_descending` from my `challenge_config.yaml`.

**Expected behaviour**
Altering `leaderboard_decimal_precision` and `is_leaderboard_order_descending` should be reflected in the leaderboards on EvalAI.

**Observed behaviour**
Regardless of the values of those fields, all leaderboards have a decimal precision of 2 and are sorted in descending order. Manually setting these fields from the Django admin page does result in the expected leaderboard layout, though.

**Steps to reproduce the problem**
Clone [EvalAI-Starters](https://github.com/Cloud-CV/EvalAI-Starters), edit those two fields in `challenge_phase_splits` in `challenge_config.yaml`, run `./run.sh`, upload to a local EvalAI clone, make dummy submissions, and view the leaderboard.

Is this an issue with EvalAI or could there be something wrong on my end?
