This issue is indeed related to the time format issue I pasted the URL of in my OP. The article was also updated yesterday with the workaround steps.
The date format changes only need to be performed within Security Status Summary on the Home page, through Preferences -> Logs and Reports, any date format other than DDMMYY works fine, and no date format changes need be made to Windows.
#EDIT# You can also just change the Date separator and leave the date format unchanged as DDMMYY, any date separator other than the slash / works fine.
