I am attempting to enter dates in sheets and they keep disappearing?
Could be a couple of things:
- If you have tasks indented below - it will disappear (but generally tell you with a pop-up) that it is dependent on sub-tasks
- If you have dependencies - you might have set the date before the prior activity date
- Sometimes having a start date, end date and #days can affect this. You have to do this in the right order if you are changing something previously populated
This is likely due to predecessors. Try removing all the predecessor values then change the dates.
