"paste in words' skipped a bunch of words. How can I tell which ones?

I made a Clozemaster collection from a list of unfamiliar words that I have come across in German news. I used the “paste in words” options to input the words to my collection. Asking it to find sentences for me.

But I realize now that this option skipped a lot of the words.
How can I easily find out which words it skipped so I can make sure find my own sentences for them and input them again?

Is there a way I can download the collection? Then I can write a script to search for all the words and see which ones aren’t showing up.


I believe it’s because there are no phrases with such word.


Yeah, that makes sense.
But I think it’d be helpful to easily see which ones didn’t make it.
