It could be a couple things depending on your situation.

Have a look at the site Navigation Settings. Check Navigation and make sure that under Current Navigation you have anything either Checked (Pages/Subsites) or add manually links and compare the results.

It may also be the Master Page you are using (if it is custom). Try changing the Master page back to the seattle.master and compare the results.
