I was following the competition and noticed that the coaches got distracted, when they went to the table, the change was denied by the TO.

6.6.12 Before the first attempt and between two attempts the Team Official / athlete must
notify and sign the next attempt on the Athlete’s Card; both for declaration and
automatic increment. This signature enables two (2) changes.
If the Team Official / athlete fail to do so before the final call (30 seconds), the
athlete will be called according to the automatic progression.
When an athlete is taking consecutive attempts (2 minutes allocated time), the
Team Official / athlete must declare the next attempt within the first thirty (30)
seconds after being called, even if it is the automatic increment.
Failure to do so will forfeit the two (2) changes allowed. The athlete will then have
to take the automatic increment. (See TCRR 7.10)
