Revert Transaction Batch Process

Summary:

We've been scheduling Revert Transaction processes on a daily basis because we have daily imports, and there might be transactions with duplicate transaction number under the same transaction type in it. Recently we noticed the sub processes starts to be triggered twice

Content (please ensure you mask any confidential information):

For example, our process runs every day at 2:30 AM ET, and looking at the log,

Revert Incentive Transactions is submitted at 2:30 AM, not a problem.

But the subsequent process Revert Incentive Transactions: Revert Credits in Batch is submitted twice, both at 2:30 AM, the all ran successfully. I am wondering if this is because there are two many records that need to be reverted, so the revert credits in batch had to run twice to process all the records? There's no log for us to review to confirm, anybody know any documentation that points to this?
