Automatic self-publishing problem

hi, I configured the module only that any change I make to an article or for each post I insert the plugin automatically publishes it on my twitter profile even if I choose the option not to publish it. Why? What am I doing wrong? In the advanced settings activated under “Do not post Tweets by default” then I can decide whether or not to publish it on the twitter profile from time to time I insert a new article or do I have to purchase the pro version for not having the automatic publication without choice?

Thank you

Kind regards
