Import Bookmarklet, Japanese (error)

I study Japanese, and when I import a lesson using the import bookmarklet, it doesn’t separate words - it makes each sentence into a “phrase”. I haven’t had this problem before. I thought I should point it out to the developers.

Thank you for your patience. Our technical people will look into it. Do you have the problem if you copy and paste the imported article?

No, not at all. Doing it that way works perfectly fine.
