Hi all,
I've defined a Custom Field in my project, of DateTime Picker type. Accordingly, the search template is Date Time Range Picker (the only other option would be "none", which is no good).
That Custom Field is used in a Filter like this:

Not sure what I'm doing wrong, but the resulting sorting in the Dashboard where that filter is used is wrong. (see screenshot)

Nevermind the differences in datetime formats, the real issue is that the sorting order is quite wrong and doesn't seem to follow any particular logic, and it's the same if I reverse the sorting.
Any suggestions?
Many thanks in advance for any assistance.
