Donations submitted twice

I accidentally sent a tithing donation in two batches and would like to know how to delete the batch that it is in. One batch has three donations then there is a batch with just the one donation repeated which I would like to delete.

You will probably need to ask your ward clerk to help you resolve this issue.

Assuming you are a clerk you'll need to contact the Global Service Center. There isn't anything you can do on your own to delete a batch or any donation in a batch.
