Illegal Feinting

#1
Hi all,

Quick question regarding the correct action to take if a player illegally feints during kicks from the penalty mark.

The LOTG state that an indirect free kick should be awarded and player cautioned for unsporting.

I can't seem to find the correct action during kicks from the penalty mark (penalty shootout) as a free kick obviously can't be given?

Is it a retake or recorded as missed?

Thanks in advance!
