Duration and start and end dates calculated by the predecessors

Hello,

I'm putting my predecessors separated by commas and I'd like to understand why the start date, end date and duration columns aren't being calculated automatically?

I'd also like to know how to set dates, as is possible in MS project?

I want to set dates and not necessarily have fixed intervals, they need to vary according to the dates of my predecessors, but in Smartsheet it doesn't work.
