When booking a time off, the "days that will remain" information does not take into consideration future time off bookings. This leads a user to think that they may have more time off days remaining than what they actually have.
On testing this, noticed that the "As of ..." line doesn't change when the "Start" date is altered e.g. Set Start date to be 01/12/2016 -> The "As of ..." line reflects the date. Then change the Start date to 20/11/2016 and the "As of ...." line remains displaying Dec 1, 2016.
A wee bug I think!
