Hello! My interface (sorry dont know the correct terms in english) looks like this:
How can I change it so it shows the real title of the cards again and not dots only?
Second Problem:
I added cards to a deck that does not appear on my main screen (where all the other decks are) neither in the list on the left of the picture above. When I search for them they do appear but I would like to be able to study them in a deck.
Would really appreciate your help!
Can you post a screenshot of that as well? The one above is not scrolled down enough to show the decks.
If there is a deck that is not displaying for you anywhere, it might be placed inside another deck. If it is located there unintentionally (drag-and-dropping can easily lead to such accidents), you can just take it back out. If you want it to remain a subdeck, you can click a + sign left to its parent deck to see it on the main screen, or, similarly, the â–¶ arrow in the Browser side menu.
Thank you for your reply!
So the problem is that if I add a card it lets me add it to the deck:
Regarding the other issue: As you can see on the pictures above (in the middle of the picture), all the titles of the cards are gone and there are only 3 dots each. Do you have any idea how to fix that?
Thank you!
Sorry I might have replied to my own post so lets try this again 
That doesn’t look right, indeed. The only other suggestion I have is to try running Tools → Check Database and restarting Anki. Also try disabling add-ons if you have any.
I agree with Eltaurus – Check Database will usually solve the “deck does not appear” issue.
If that doesn’t also solve the “[…] in Browse columns” issue, then make your way through the rest of the Troubleshooting Checklist. Troubleshooting - Anki Manual
Doing the “check database” has done the trick! Both issues solved!
Thank you so very much; I really appreciate you two!
Thank you!
