An engagement studio program is enabled to repeat.

 If an engagement studio program is enabled to repeat, the prospects are eligible to repeat after one day and can repeat three times, and a prospect remains on the program recipient list, then the prospect will start the program over at the beginning after waiting one day (A). This is how repeating engagement programs work in Account Engagement. The prospect will not be prevented from restarting the program (B, D) unless they have reached the maximum number of repeats, which is three in this case. The prospect will also not restart the program immediately ©, but after the specified number of days, which is one in this case. References: Repeating Engagement Studio Flows Introduction
