Custom taxonomy issue

Hello

I have created a new custom post and a new custom taxonomy. When I go to add a new taxonomy to the new post, it selects all the categories automatically when saved, when I have only selected one.

Older categories and posts can be saved and categories added/removed ok, just these new post types and taxonomies.

Getting this error in the logs:

WordPress database error: [Duplicate entry ‘39067-0’ for key ‘PRIMARY’]
INSERT INTO term_relationships (object_id, term_taxonomy_id) VALUES (39067, 0)

Any ideas?
