<p>In an administrative sense his is a logical error. The UAs should not be a subarea of the ceremonial county. However in a geometrical sense it is not wrong of course, although you could consider it redundant.</p>
<p>A ceremonial county boundary is defined using a different process to administrative counties, and in theory there can be temporary divergence (if the admin boundary is changed by law and it takes a while for the ceremonial county to catch up) or, indeed, permanent divergence (such as County Durham which is split between two admin counties).</p>
<p>I would be in favour of removing the subarea links in the case of the Berkshire UAs.</p>
<p>A ceremonial county has no level because it doesn't need one - there are no ceremonial entities at a higher or lower level.</p>
