"Next" button is missing from Acrobat Fill & Sign

Hi, I have changed my university installation from "Shared Device" type to "Named License" and due to this change I have completely reinstalled Adobe CC (I'm running on Windows 10). I don't know whether this has something to do with my issue, but I would say it's good to say 🙂

Before, when I signed a document, I had a "Next" button next to "Close" button (see here), which allowed me to make document read-only and send it via Adobe Cloud secure storage. However, now this button is missing and securing & sharing the document is lot more time consuming (like 20x), which gets me a bit crazy (I need to sign usually multiples per week and it just slows me down from my real work, when there is no way how to batch process the documents). Does anybody knows how to make the button appear again? I have searched the internet, asked the hotline, but nowbody knows... 😞
