Taxonomy API returning invalid categoryIDs inside Business & Industrial -> Office -> Office Supplies

[refresh_ecommerce]

Just making a standard API call to the following URL:

https://api.ebay.com/commerce/taxonomy/v1/category_tree/0

and 99% of the returned data seems to be fine but one area which we list in is returning invalid category IDs, parsed example result below:

<option value="25344">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding</option>
<option value="11834">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding --&gt; Other Office Filing &amp; Binding</option>
<option value="25345">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding --&gt; Binders &amp; Supplies</option>
<option value="25346">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding --&gt; Files &amp; Supplies</option>
<option value="61755">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding --&gt; Binding Covers &amp; Spines</option>
<option value="61756">Business &amp; Industrial --&gt; Office --&gt; Office Supplies --&gt; Filing, Storage &amp; Binding --&gt; Binding Machines</option>

 
These category IDs aren't the same as the ones on the ebay UK website but it seems to affect most of the Office Supplies category.

I can't find anything inside the JSON result that would indicate the correct values.

E.G. Binding-Supplies Returns results for category ID = 148459 but that value isn't in the returned taxonomy data.
