When performing a sort by column in on project schedule, the sort sticks when navigating to another project schedule even when the field in the initial sort is not present in the new project schedule.
This causes the task order to appear correctly in numerical order when in fact, it isn't. This means when the user selects line items to indent/outdent, the buttons don't appear at the top of the screen.
I'd suggest removing the sticky sort functionality so this doesn't continue to cause usability issues with the user base.
