Hi,

Sorry for the delay.

1. It appears you want to display only events that are in progress. By default there is no such filter included so you will have to add following hook in your theme or child-theme functions.php file:

// STEC MOD: Register in_progress filter
add_action('wp_footer', function () {
    if (!wp_script_is('stec-js')) {
        return;
    }
    ?>
    <script type='text/javascript'>
        (function($) {
            $(function() {
                $.stecExtend(function(m) {
                    if ('1' !== m.glob.options.in_progress) {
                        return;
                    }
                    m.calData.filterGetEvents = m.calData.filterGetEvents.filter(function(event) {
                        var startDate = moment.tz(event.start_date, event.timezone);
                        var endDate = moment.tz(event.end_date, event.timezone);
                        var now = new moment();
                        if (now.isBetween(startDate, endDate)) {
                            return true;
                        }
                        return false;
                    });
                }, 'beforeReturnGetEvents');
            });
        })(jQuery);
    </script>
<?php
});

After this hook is inserted add to your shortcode "in_progress=1" like following:

[stachethemes_ec in_progress=1]

2. Go to Dashboard -> STEC -> Fonts & Colors -> Custom style tab and insert this style:

.stec-layout-single-media-small .stec-layout-single-media,
.stec-media-small .stec-layout-event-inner-intro-media {
    display: none !important;
}

Okay, in that case replace following lines of the code:

                        if (now.isBetween(startDate, endDate)) {
                            return true;
                        }    

with:

                        if (now.isBetween(startDate, endDate) || now.isBefore(startDate)) {
                            return true;
                        }
