Hello Thanh,
Thank you for your question about viewing the lead time. It isn't shown on the page at this time, but we will soon have a software update that addresses this.
You may re-add a snipe if you want to be certain. You do not have to delete the snipe first - the software will overwrite the old value.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
