Question: I'm having an issue with Unique Events and Total events. I don't really understand why unique events are greater than total events (image attached: <https://analytics-a-googleproductforums-com.googlegroups.com/attach/584c3c65bd24cfec/Screenshot%20at%202013-05-14%2017:00:40.png?gda=9qkpgUYAAADqfLbDOUx1KZ9vP-6pB8mH0QevsNJBCwpb2zqmxh9R_FqJw8mf6kYUxitGhb4bDE5x40jamwa1UURqDcgHarKEE-Ea7GxYMt0t6nY0uV5FIQ&view=1&part=4>). 

Someone can explain how this is posible?

Answer: 
Found the thing: you will see that "Unique Events" are great than "Total Events" when you look at an event category or action, put "Event Label" as a secondary dimension and the event has been triggered some times with no label input. Google Analytics hasn't the option "(not set)" for this particular dimension, so it just doesn't show you those events in the Total Events Count, but still counts as "Unique Events" all the users that executed this particular event category / action.
Google has deprecated (renamed) *Unique Events* metric as it was seriously confusing. We are expecting to see a number of times event with unique combination of category / action and label happened per other dimensions in report. Instead GA calculated a unique combination of every dimension in the report!
Now, this metric is deprecated and renamed to legacy. 
New one: Unique Events is giving expected results.

I written about why total events are higher than in my blog as too many questions.
