Hi,
Please go and update the theme to version 7.3.5 by do following this guide.
After update the theme to latest version, don't forget updates plugins via Appearance > Install Plugins > click on "Update" tab. ( NOT Plugins > All Plugins - please don't understand wrong. )
When you done, edit a post and the issue will gone. If you didn't see the issue gone, on edit a post screen - please Press Ctrl + F5 sometimes to clear all the cache - and it should works now.
Best Regards,
