Once an advanced layout is created, changing those options for a date field inside the advanced report designer is not supported. This item is currently on the list of features to add.
You should be able to change the way this Datetime is getting output with the TTOC() function. To do so, simply edit the datetime field in question, and in the output expression for this field, place the field inside a TTOC() function. So, if the field is, for example, HISTORY_START_DATE_TIME_LOCAL, the output expression would then become:
TTOC(HISTORY_START_DATE_TIME_LOCAL)
If this does not work, you can delete the advanced layout for the report, make the change in step 2 of the quick report wizard, and then re-create the advanced layout and re-add your custom layout changes inside the advanced report designer.
