Got it. I think it does make sense to allow fields that are flagged to clear on focus, to also clear on submission if the value = the default value. Again, it'll be in the next release.
Here is the quick fix:
in lib_ajax.php (~line 155) just before:
// check if fields needs to be cleared
add:
//check if fields needs to be cleared
$obj = explode('|', $field_name,3);
$defaultval = stripslashes($obj[1]);
if ( $params ['field_' . $i] == $defaultval && $field_stat[4]=='1')
$params ['field_' . $i] = '';
in lib_nonajax.php (~line 99) just before:
// check if fields needs to be cleared
add:
// check if fields needs to be cleared
$obj = explode('|', $field_name,3);
$defaultval = stripslashes($obj[1]);
if ( $_POST[$current_field] == $defaultval && $field_stat[4]=='1')
$_POST[$current_field] = '';
