The Events Calander: conflict with Nivo Slider in magzimus theme

Using the Magzimus theme that incorporates the Nivo Slider.

All posts that are not part of the “Events” calendar and category show up in slider just fine.

Any post that is flagged as an event to the plugin do not get selected for the slider. I debugged and found only non event calendar posts come back in this function:

function get_slider_posts($maxposts = 99) {
global $post;

$posts = get_posts_by_meta(‘showinslider’, 1, $maxposts);

Just taking a post out of the ‘event’ puts it back into the slider.
Stumped on this one.
