Short Code Parameters not working

The plugin works great and has everything I need, but for some reason the short code parameters don’t seem to be working. I’ve used this short code:
[pgaf_post_filter show_date=”false” show_author=”false” show_category_name=”false”]
Unfortunately, it still displays the date, author and category name. I’ve done a workaround, where I’ve added css coding to not display those div classes, but that’s obviously not ideal.
