Why is there a Red X next to my time

You have posted a time on the leaderboard for a chosen competition and see a red cross "X" next to your time:

• The cross "X" is an option for you to delete that given time if you feel that the time in question does not comply with the rules, you will be prompted with a confirmation box to complete the removal of the time from the leaderboard, once this has been confirmed, it can take usualy 15 minutes for the leaderboards to update.
