When I add a post, and type in a new tag name on the right and click, "Add" it is not adding, it shows the "Add New Tag" with my text typed over it.
When I select tags from ones I used before, I add them, they appear below the text box, with the small X to delete them from the post, I click Update or Publish, the page refreshes and the Tags are gone within the Post edit, but are on the post. Started with 2.9, trying out 2.9.1 and still not working.
