error appears after update v1.8.1

Hi.. Sir

When I got the update to version v1.8.1 and have done it successfully, making articles that I created with bulk post mode so it doesn’t work properly.

1. as I usually include ai assistant, I don’t find the results of the article that I created with bulk post mode.
2. I tried without using Ai assistant but there was an error that I found in the log. Failed to generate content using AI writer: – error: Error: Invalid request submitted to the completions API, result: stdClass Object ( [message] => you must provide a model parameter [type] => invalid_request_error [param] => [code] => )

and also besides the main error above, there seems to be an inaccuracy in the “running status icons”. The status icon is signaling red but I see in the activity log and refreshing the browser that the plugin is still running to regenerate the post from the heading.
