Category code 'ZX - Paintshed template' is obsolete.
Category codes are used to assist with classifying assets by type. Some catefories have special meaning, and category 'zx - Paintshed Skin' is one of those. This asset type is now obsolete, and the category code should not be used.
Change the 'category-class' tag value in config.txt to a category that is appropriate for the asset type. See: Category-class.
