You can delete both individual and bulk checklist logs. This comes in handy when you've had a few faulty entries. Let's see how to do so.
To delete a log, head to the Checklist dashboard from the sidebar menu. From the 'My Templates' tab, open the checklist which has a log you'd like to delete.
Next, open Logs in the checklist tab. Select the checkbox(es) against the log(s) you'd like to delete. This will pop up a delete button at the bottom of your screen. Click on that to delete your selected log(s).
