The Gantt Workflow chart timeline starts at 2010, and I can't scroll forward to 2016 Reproducible: Always
Hmmm, possibly you opened the "Basic project" template? This is a small project created in 2010. Gantt chart only shows the range of the scheduled tasks so shows 2010. To change things you can edit the start/finish times in the Main Project dialog and reschedule. I can see how this is confusing, so need to think about it.
Template system changed. Old templates not used anymore.
