Mike,
Sorry that you are seeing this issue.
Can you please check if the issue persists in a new workspace as well?
Go to Window > Perspective and select Reset Perspective. Add the History view once again and see how it works. If resetting the perspective does not work, then try opening a new window (menu Window > New Window) and add the History view.
It looks like a known issue with the History view in Java Perspective in Eclipse Mars. MyEclipse 2016 CI 3 is based on Eclipse Mars 4.5.1.
Please check this bug report and see if any of the suggestions help fix the issue at your end :

Apologies for inconvenience caused. Let us know how it works.
