No problem, I wasn't clear enough with the "apply this patch" :)
For screenshot #2 (with the N on top of the avatar) that has to be a media query issue, which I mentioned in my answer. Not sure if you know about them but the super short explanation is they basically are pieces of CSS that get applied based on window size. That happens when you make the window smaller. You'll have to look for the exact media query that is changing the CSS and, for that media query, apply a custom media query for the notifications plugin. The CSS I've provided is for the full width one.
For screenshot #3 I'm not sure why that is not being displayed. I don't think it is related to the changes I've proposed here unless I've added a bug in the patch. You could try rolling back the changes and see if it works.
