Date values export as plain text instead of date values when exporting transactions from the grid to Excel
In Aeon 3.9 the date values would be exported as a date value which you could then sort chronologically. In Aeon 4.0, the new values only allow you to sort them alphabetically unless you manually remove the AM/PM text from all the cells and change the format of the cells to a date format.

When you set the StaffPreviousPassword to 0, Aeon should default to checking a minimum of 4 unique passwords before an old password can be reused. Instead, a bug is causing the system to read the 0 as a null value, which in turn made it to unable to recognize any passwords. Until the bug is fixed, do not set the default value to 0.
