Flash cards bugs

when I open a lesson I’ve already read and I want to review the words (flash cards). I click on the flash cards and there is 0 to repeat. but as soon as I move the dot over the green line. I move between the text. It shows me the words (23 words) in the flashcards to repeat. video from cell phone Lingq Flashcards - YouTube

Can you open the video?

Thanks, we will investigate this.
