Native Shopping ads from Amazon in my WP site blog posts via the Sidebar widget

I am trying to use the ad inserter to insert Native Shopping ads from Amazon into my WP site blog posts via the Sidebar widget. When I save the config nothing shows on my pages. These are the settings. 
Ad Inserter 2.7.10
WordPress 5.8.3
This is the code in the ad inserter block
<script type="text/javascript">
amzn_assoc_placement = "adunit0";
amzn_assoc_search_bar = "true";
amzn_assoc_tracking_id = "thekayaklau0b-20";
amzn_assoc_search_bar_position = "bottom";
amzn_assoc_ad_mode = "search";
amzn_assoc_ad_type = "smart";
amzn_assoc_marketplace = "amazon";
amzn_assoc_region = "US";
amzn_assoc_title = "Shop Related Products";
amzn_assoc_default_search_phrase = "kayak accessories";
amzn_assoc_default_category = "All";
amzn_assoc_linkid = "e27e78ca0a2f21953dcea2540d7a5c3b";
</script>
<script src="//z-na.amazon-adsystem.com/widgets/onejs?MarketPlace=US"></script>

I have the ‘manual’ button set to ‘posts’ and insertion disabled. I have Widget checked and set to ‘sidebar. Nothing set on the ‘lists’ tab. 
On the widgets page I have the Ad Inserter using the block configured above in the Sidebar area along with 3 other blocks for the Sidebar. The 3 showing are ‘Search’, ‘Recent posts’, my Facebook short code. These other blocks display properly on all my post pages.
