Some important flashcards cannot be added to my deck

So I’ve been trying to import some shared anki decks but for some reasons it would show that some flashcards cannot be imported, what do I do?

What does the after-import screen tell you about why those notes couldn’t be imported?

It doesn’t tell me why, it just shows this

The Details dropdown should reveal more info about the problem. You can try enabling the “merge notetypes” option when importing; it might be related to notetype updates.
