Thanks for the feedback! I know it might seem like a bug, but it’s on purpose. The idea was that there should always be a day, and with my developer logic, I just enforced that. Now, I realize it’s in fact a bit silly, and we should simply allow day-free protocols, since in most cases a protocol will anyway just span a day. For multi-day protocols, the user can simply insert a day, and then we assume everything at the beginning starts on ‘Day 1’.
Technically, that means a bit of work on the editor logic, but I do hope I can work something out in a future update not too long in the future. In the meantime, you will have to forgive that ‘Day 1’ header, and pretend it’s not there
