<p dir="auto">The command db.schema.visualization contains loops suggesting that nodes have relationships with other nodes of the same type, but this it not the case in this graph.</p>
<p dir="auto">I include a screenshot below in which you can see the output of db.schema.visualization and also a Cypher query showing that there are no nodes with this loopback relationship.</p>

<p dir="auto">This question looks like a duplicate of <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="55422803" data-permission-text="Title is private" data-url="https://github.com/neo4j/neo4j/issues/3872" data-hovercard-type="issue" data-hovercard-url="/neo4j/neo4j/issues/3872/hovercard" href="https://github.com/neo4j/neo4j/issues/3872">#3872</a> , however I'm unable to upgrade neo4j any further than 2.2.8.</p>
<p dir="auto">A basic query to return the searched Node works correctly, however when I try to delete the node with DELETE, I get the following error:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="org.neo4j.kernel.impl.core.NodeManager.isDeleted(Lorg/neo4j/graphdb/Node;)Z"><pre class="notranslate"><code class="notranslate">org.neo4j.kernel.impl.core.NodeManager.isDeleted(Lorg/neo4j/graphdb/Node;)Z
</code></pre></div>
<p dir="auto">A sample of the query I'm using is as follows (the queried node definitely exists):</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="MATCH (n {comment:&quot;Adding subbcomment to midland&quot;})
DELETE n"><pre class="notranslate"><code class="notranslate">MATCH (n {comment:"Adding subbcomment to midland"})
DELETE n
</code></pre></div>
<p dir="auto">I've tested this behaviour across Neo4J Enterprise 2.2.1 and 2.2.8, and the error occurs across both. I've also re-downloaded the packages and the error persists.</p>
<p dir="auto">Noteable behaviour: through the webadmin, if I click and examine the returned node and click the 'Delete' button, it is successfully deleted.</p>
<p dir="auto">Is there some sort of dependency or JAR that I am missing perhaps? Any help is greatly appreciated.</p>
