Problem with duplicate Woocommerce posts

I am attempting to pull products from my child-sites using the following shortcode:

[netsposts exclude_blog=”1″ thumbnail=”true” size=”225,291″ order_post_by=’date_order desc’ include_link_title=”true” taxonomy=”community-catalog” post_height=”400″ auto_excerpt=”true” excerpt_length=”500″ column=”3″]

It works great except that as soon as I started adding more than one test product on child-site #3, it created a duplicate listing on my parent site page where the shortcode is used of each of the three new products I added (but not the original first one). The duplicate listings link to my parent blog (#1) as the author but each product (post) link goes to the original product in my child-blog (#3). No new products have actually been created on the parent blog and the images do not appear in the duplicate listings. I can’t figure out how to get those new listings not to appear. I’ve tried including just the child blog (removed the exclude_blog code), but that made no change.

Here’s what it looks like:

Any help would be appreciated – if I can get it to work right, this plugin is exactly what I was looking for ??
