When there is not a consistent default leave start month set under the configuration tab, leave profiles are permitted to have different start months.

When viewing the Management tab the default year shown will be your current leave year. 

Please note, this may not be the current leave year the employee you are viewing, as they may have a different leave start month.

For example:

If your leave profile has a start month of January and today is 21st March 2017, when viewing the Management tab you will see 2017 - as this is your current leave year.

When viewing the allowance of an employee with a July leave start month, to see their current requests you would have to use the toggle to select 2016, as they are currently in their 2016 leave year.
