Custom Type Category not working

To create a Custom Taxonomy with Types, you can use this Guide:
https://wp-types.com/documentation/user-guides/create-custom-taxonomies/

Then, you head to your Post Type > your_taxonomy and add terms

After, you head to your Post Type > All > your_post > Edit or New and add (check or write) the Taxonomy in the Meta box that will appear on your lower right of the screen

If this does not work, please share some more details so we can understand.

Thank you
