I am curious about this, too. However, my case is slightly different. My V14 personal use licensed laptop has the AI settings page you show for V13.3.1. My V14 primary licensed desktop has the AI settings page you show for V14. Somehow, the 2 upgrades to V14 on 2 PC's was different.
I submitted a support ticket with WRI support, but I haven't had a response that solves the issue. The support engineer said he forwarded the issue to the developers. That was many weeks ago. My preference is to have V14 use the AI settings you show for V13.3.1.
