Hey Tom,
The events admin columns are indeed a bit crowded to begin with, and then the addition of whatever Analytics-related plugin you have is adding its own columns there which is just making it too cramped.
I’m sorry you’ve dealt with this thus far – fortunately, you can head up to the “Screen Options” tab in the top-right of the admin page there, and click it, which will reveal a drawer of checkboxes corresponding to the columns.
Un-check any columns you don’t need to display there, and that should neaten up the column view substantially! 🙂
Let us know if this helps and if you have any other questions.
Thanks,
George
