your video example is made with “ShortCodes” Beta? If yes, the problem should be fixed with the Beta I have running here on my side.
Regarding the second part, there is one container on your side which is wider than the others. I suggest to first identify the container causing the issue. I would delete one and check if the design is ok. If not, then delete the next one. Continue until the design fits and then check the container (and subcontainers) what’s wrong.
On the pictures, two are correctly wide and two are not - when comparing it is noticeable that three additional entries are displayed at the bottom, exactly where the text is. I guess I have to make the container wider – or am I thinking wrong?
