Task not scheduling properly

edited 12/09/19 in Smartsheet Basics

I have a plan in a smartsheet which isn't scheduling as expected. several task that have no predecessor seem to be staying put. I'd expect them to move to the project start date.

I can find no option to change constraint type.

I've exported it to MS Project and it exhibits the same behaviour until I review the Resource sheet and delete all its contents, then it schedules correctly. I'm unsure where to find this info in smartsheets. See attachment.

How do I ensure the plan in smartsheets schedules correctly?
