Hi,
I have a report in which data is being displayed incorrectly visually for a field.
As you can see below I have the following three dates that are ordered.

Visually they appear as 07/12, 12/08 and 09/12, when in reallity the data being displayed for the 12/08 is the one of 08/12, and if I order the data it appears corrected.
You can see below another example:

Do you know why this bug happens?
