AI Content Editor > Tags

When I "Run Post Editing" from the "AI Post Editor" page and prevent all editing except for the Tags section, the resulting response is a series of numbers. It appears having spot checked them and running the same request through Azure Playground identical GPT model (3.5 Turbo 16k), it would appear to confirm this. This started happening after checking the option to "<b>Do Not Add Inexistent Tags:</b>", but persists even after unchecking it again (and saving changes). I am targeting product (posts) and those tagged with "test". This problem was not initially present, but started either when I changed the prompt to include the %%post_excerpt%% or when I checked the tickbox for the first time to only use existing tags.
