Thanks for the screenshot.
Your site’s Event Meta isn’t standard. This is an example of standard Event Meta display: http://cl.ly/3d0b0D3z270k
Notice there’s not even a separate “Time” area on the standard view, but yours has it: http://cl.ly/1H1P092J342S

Please follow our Testing for Conflicts guide closely, including testing with Twenty Fifteen or a similar theme — and making sure you don’t have any theme overrides or hooks in use.
If necessary, you may need to contact your theme’s Support to see if they can help in any way.
I hope you can get to the bottom of it.
