I still can see it in the .opf file:

 <meta name="calibre:user_metadata:#scaffale" content="{&quot;datatype&quot;: &quot;text&quot;, &quot;display&quot;: {&quot;is_names&quot;: false}, &quot;is_custom&quot;: true, &quot;is_multiple&quot;: &quot;|&quot;, &quot;name&quot;: &quot;Scaffale Kobo&quot;, &quot;#value#&quot;: [&quot;Narrativa italiana&quot;], &quot;search_terms&quot;: [&quot;#scaffale&quot;], &quot;category_sort&quot;: &quot;value&quot;, &quot;is_multiple2&quot;: {&quot;ui_to_list&quot;: &quot;,&quot;, &quot;cache_to_list&quot;: &quot;|&quot;, &quot;list_to_ui&quot;: &quot;, &quot;}, &quot;colnum&quot;: 1, &quot;table&quot;: &quot;custom_column_1&quot;, &quot;link_column&quot;: &quot;value&quot;, &quot;is_editable&quot;: true, &quot;column&quot;: &quot;value&quot;, &quot;kind&quot;: &quot;field&quot;, &quot;is_csp&quot;: false, &quot;rec_index&quot;: 22, &quot;label&quot;: &quot;scaffale&quot;, &quot;is_category&quot;: true, &quot;#extra#&quot;: null}"/>

but I cannot see the column anymore in Calibre...
