Looking at your HTML, the format for date you have specified in the setting is
$SITE['dateOnlyFormat'] = 'd-M-Y';
and this is indeed in the HTML of the page, however as soon as the page updates for the first time it changes to d/m/Y
I checked the JS and it looks like it is taking the date format directly from your clientraw.txt, which has d/m/Y
See if this can be changed in WD or Im afraid we will have to wait for the expert (Ken)
Sorry, I dont use Saratoga myself.
