Thank you very much for your kind words!
I've looked into the code part responsible for displaying the date, and there appears to be a minor issue there exactly as your described. To resolve it, you will have to make a change on one of the plugin files, just follow this guide:
0. Before starting, make sure to have a back-up copy of everything. I once accidentally deleted my website root directory, and struggled without back-up.
1. Open up the wp-content\plugins\ajax-search-pro\includes\views\asp.shortcode.date_filters.php plugin file on your server and navigate to line 28, which is:
$_dft_v = $_dff['date'];
.. this is the problematic code.
2. Change that line to simply:
$_dft_v = $_dft['date'];
3. Save the file, and re-load the search page, it should be okay now.
