Go into the calendar settings in the app and turn off the calendar that is light blue (the same color of the bar next to each entry.

Then go to the email account online and ensure that you have the setting 'automatically accept appointments' turned off.

Did you download any third party calendar app? I would try uninstalling it immediately.
