I have completed the spell check on a text. The book icon at the bottom has a red X which indicates that there are still mistakes. I click on it to point the missing mistakes and it says : "spell check done. the text ignored was not verified" (my version is in French, so this is the approximate translation) After doing that, I still have a red X on the book icon instead of a green check mark.

I also tried "accept all modifications" in the revision tag, and no green check mark.
