Answer:
Some of the errors that appear with an event temple utilize the settings in your browser to dictate what language they are translated into. In order to fix this problem, you will have to change some settings in your browser.
Open Google Chrome
Access your settings by entering chrome://settings/ in your address bar
Search "Languages" in the search bar that says Search Settings
Click on the Language drop-down
Find the language you would like your errors to be in from the list (Note: If it is not there, click Add Language and find it.)
Click on the three dots on the right side of the language you want and select Move to Top
Once these steps have been taken, errors should appear in the right language.
