Memrise on the computer won't sync with my phone

I’m on editing my deck called “1500 Words - Key to Korean” and the changes are not showing up on my iphone Memrise app. I have the course on the Memrise app, but the words that I changed using the computer are not showing up on my phone. Is there a way to sink the two?

There’s an issue with users’ courses known as phantom words.

Three steps to resolve it:

  1. Go to database in the edit section of a course and correct words
    (in the section called Database, not in the course directly)
  2. Install a userscript in your PC browser and run it
  3. Log out of the app and log in again (or clear data in the app)
