I have a course that’s about 3,000+ words. When I go to add new words, it usually tells me if the word is already in the database (using my own) or not. It just continues to search and never finishing it. In order to get around this, I could only search from the database itself, and not from the word creating area (level area). It’s very annoying and time consuming, yet if I want to add the same word again, I can’t. Which makes it hard to continue doing my course.
