Few things about this plugin.

On creatng an event, I cannot get the monthly calendar to display using shortcode.

My event does not show the featured image when opened.

On opening an event, there seems to be an added <aside> section added in my html ()widget area. How do i rid this from my page?

Finally are there default styling with the plugin as apart from the text, it looks very bare.
