Unclear text, when generating an article using AI internet.

Hi, I am customizing a plugin on a website. https://wfxfx.com/wp-admin redacted redacted YOU can go to the plugin settings and see how I did everything. When generating an article, the text often has obscure words, symbols, words without spaces, etc. Example article - https://wfxfx.com/test-your-forex-trading-skills-with-mt5-trade-simulator/ It doesn't happen every time, but it happens. I look carefully at the log. I take the same promt from the log, send it to chatgpt web and it generates the article much better, without these problems. Do you have any ideas what I am doing wrong? It seems to me that the plugin is adding some extra tasks to my promt. Looking forward to hearing back from you, thanks!
