This is an issue that I have noticed too. A work-around is to install Modern Tribe’s Advanced Post Manager plugin and the issue will resolve itself.
Alternatively you can also download/install the plugin from the Events admin screen. Near the top there’s a “PSSST! Looking for filters?” link.
TEC Support – As for the root cause, if you compare the CSS when the APM plugin is active to when it’s not, you will see why the title column is squished. Yes you can adjust the column width with custom functions, but it should be addressed in another manner.
Hope this helps.
