The questions are not lost, but they have been moved by the upgrade process.

In the Course category where the questions used to be, you should find a new course called something like "Shared teaching resources for category: Thinking". In that course, go to More -> Questions banks, and there should be a question bank with your questions.

That is just what the upgrade does automatically. You can, of course, rename things, or move things around to organise them however works best for you.

The secret to working out this sort of thing is to use the 'Inspect' option in your web browser, to look at the HTML of the page. You need to find something sufficently unique to make your rules apply where you want them without causing unwanted side-effects elsewhere. But, also, if your browser Inspect tool, you can probably try editing style rules on the fly, which is the best way to iterate and find the rules you need.

However, I can't see a way to get the things you want. The table at the top of the review page does not have useful ids on the rows (which is a bit of a missed opportunity, because in the code behind this there is a value that could be used to make a sensible class for each row. And, only having the id of the category, and not all parent categries, is like that for performance reasons.

The CSS to hide the marks when reviewing a quiz is probably:

body#page-mod-quiz-review .que .info .grade {
    display: none;
}

If you want to limit that to just one course or quiz, you can change the first bit of the selector to

body#page-mod-quiz-review.course-2
body#page-mod-quiz-review.cmid-123

Jetz soll ich das Deutsch verstehen, weil ich seit ein Jahr Deutsch lernen.

(Now, as a moderator here, I need to point out that the language of this forum is English.)

I suspect that the cause of this issue is MDL-79540, which still seems to be an issue. In more recent Moodle versions, it does not cause an error. It just makes categories disapper in the UI, which is also bad.
