Ok, got it!

At first it looked like it was a JQuery issue but it appears to be a combination of JQuery and WordPress. The solution is quite simple: don’t use any capitals in your “Custom Taxonomy Name”.

I found the solution on this page.

@zenopopovici: It might be an idea to a: put a note next to the field stating not to use uppercase or, even better, b: convert the input to lowercase upon submission at the same time you remove the spaces.

Note: updating the Custom Taxonomy Name will remove the category from the post but it’s still linked (it just can’t find it).
In the database, I updated the wp_term_taxonomy table (it still had all the ‘old’ names: UPDATE 'wp_term_taxonomy' SET 'taxonomy'='newtaxonomyname' WHERE 'taxonomy' ='OldTaxonomyName'. Then I regenerated the permalinks and had to rename the filenames in my child theme to match the new taxonomy name. This brought everything back to the way it was, and now I can select the categories from the list.

I have exactly the same problem. I only see a ‘0’ and cannot select anything. That’s an issue because my categories contain commas and as soon as I edit a post, the categories get split. This would be preventable if I could select from the list of existing categories. Unless someone knows a hack to not split categories that contain commas.
