The property is used to store an SSL certificate hash. It is specifically the ID 5506 entry you need to check for. That ID is the legacy property for certificate hash.
Search for the below entry in your ApplicationHost.config file and remove the property:
<property id="5506" dataType="Binary" userType="1" attributes="None" value="oXiHOzFAMOF0YxIuI7soWvDFEzg=" />
