Can't delete sections, add sections

I can’t create sections anymore nor delete ones tha talready exists. It looks like some functionality changed but we are trying to use asana for a comms calendar and it’s really messy and I can’t clean it up

Hi @Mary_Beth_LeMay,

I can seem to be able to see the screenshot you’ve uploaded, but could this be because your project is sorted by assignee, due date or a custom field?
