That is “core”, we NEVER edit core code. WordPress works, it most likely is a bug with your theme. I wouldn’t worry, hopefully the author/developer will provide good support ??
Also, knowing the name of the theme would help support volunteers research your issue…

NO! Do not edit core files.
This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
