DIV and UNIS disappearing and a2 REPEATING

Hi @Lollo_12345 I see that nobody has answered. It is always faster and better if you post a Dorico file (cut-out version) that shows the issue with an explication of what you want to achieve, and how you tried to achieve it (the steps to reproduce the issue).
(from looking at the pictures I would say they are non issues or very easy fixable ones, but maybe I am wrong). With a file, we can experiment very fast and give advices.
