I have a problem with my workflow or something.
When I move my task from "to do" to "in progress" is mandatory to put the original estimate field, after that developers time track but some times they need to move the task to "to do", when they moved it the original estimate is cleared and there is no way to put it back so the task get stuck because is a mandatory field.
[Estimate is missing]

[The time tracking field when you put the original estimate is replaced just for the remainig estimate]

[When i want to transition to "In progress" Original estimate is missing]
