[Plugin: Events Manager] Can't filter out categories v5.1.7

Please help!

I’ve been looking at this quite a bit and I can’t seem to get this working. I’ve been trying to use the shortcode and the PHP loop code to try to filter out different categories for either a page template or a post / page. I’ve tried using the following pieces of code (keep in mind they were for different pages so I was trying to filter different categories)

This is what I used for the page to try to only show category 4. This either showed everything or nothing:

[events_list category=-1,-2,-3 limit=20 orderby=event_start_date pagination=1][/events_list]

I also tried the two following pieces of code that I found on the Events Manager website and a support forum. These both either showed everything or nothing as well:

<?php query_posts( array ( ) );

if (class_exists(‘EM_Events’)) {
echo EM_Events::output( array(‘limit’=>3, ‘orderby’=>’event_start_date’, ‘category’=>-4) );
} ?>

<?php echo do_shortcode(‘[events_list full=”1″ category=”-4″ limit=3 orderby=”event_start_date”]’); ?>

On top of trying the exclude category feature, as shown above, I also tried to the opposite by listing all the categories except the ones I wanted to exclude. I haven’t had any sort of luck with this. At this point I’m assuming maybe this feature just doesn’t work. I’m fairly code savvy, but this is proving to be a real pain. I’d really appreciate some help on this!

Thanks a bunch in advance!
