I’m afraid I can’t reproduce this issue on my end. It’s possible that there’s a JS/CSS conflict on your site. Could you please try to reproduce the issue on one of the WordPress’ stock themes (like Twenty Sixteen) with other plugins deactivated? If it disappears, then you can activate the theme and plugins one by one to see which one causes the issue.
I also noticed that you are using custom field types like “hours” and “sortable_relationship”. It’s possible that these custom field types has a JS/CSS code that causes the issue. Could you please remove it and see if it fixes the issue?
