I have run through all the tabs and reports (and a bunch of custom reports) and the date format is correct for each option. The only issue I see is that the date format option does not affect date shown on the design page. No matter the format selected (Tools>Options>Units) the design page is always of the mm/dd/yy format. That will certainly cause confusion for anyone who has selected the dd/mm/yy format.
So what may be happening in the previous posts is that the date format option is actually set for the dd/mm/yy format but they are not aware of it since it is showing mm/dd/yy in the design tab.
It may also be less confusing if you include the d/m/y type description along with, or in place of, the Dec 02 2015 date example in the option list. Such as…
02 Dec 15 (dd/mmm/yy)
12/02/15 (mm/dd/yy)
02/12/15 (dd/mm/yy)
2015-02-12 (yyyy-dd-mm)
I’m on build 2.2.12 running XP(32)sp3. I love the program and I’m just trying to help you improve it.
Cheers!
