Using Version 0.9.5.4 Types.
I cannot delete an unused custom taxonomy in admin, it just hangs with the spinning wheel going round. I tried Types => Custom Types and Taxonomies => Delete Permanently.
Also a minor point I think - the description for the Custom Taxonomies on the Custom Types and Taxonomies screen in admin shows the description for the last Custom Type entered, rather than the actual description entered for the Taxonomy.
Hoping you can help, thanks.
