Sentence edit problem

For context, I am studying Chinese and recently I have noticed that when I go into a particular lesson and correct transcription mistakes, a new word is created. After the correction is made, I go back to the transcript to create a LingQ, but the app crashes instead, and I have to reinstall the app and sign in again. As of now, the problem seems to be exclusive to the screenshotted title.

I tried to recreate the problem in other lessons, but it appears to be isolated to this one lesson.

Thanks, we’ll check that.
