Document library – using categories or taxonomies with numeric slugs
In Document Library Pro, it can cause problems if you use numeric slugs for your categories or custom taxonomies. For example:

If you're using numeric slugs then you may experience problems when using the category
or term
option in the Document Library Pro shortcode, or the Categories dropdown filter. To avoid this problem, set the numeric_terms
option in the shortcode to true
for all tables that this applies to, as follows:
[doc_library numeric_terms="true"]
