Call tasks that result in dial trees not being completed

why do some dial trees not mark the call task complete in salesloft? I’ve noticed this has happened quite a bit

We don’t complete dial trees that was not navigated through because it’s a friendly reminder that we need a better number to call or we would need to complete the dial tree. After you finish calling, we recommend clicking “reset”, anyone we could not dial through will still remain. We recommend unchecking the “skip dial tree” button and calling through and that will complete the task
