It is not clear that inside the Errors tab we have a table with 2 columns and the name of the second column - Error message - could be interpreted as there is an Error in displaying the errors.

This is a better idea:
if there's no error messages, the tab Errors will be disabled, and it's tooltip will display something like "there's no errors".
