I am trying to build a Word template. It was working perfectly. I saved the document and opened it on another computer and I saw this:
All the sections were replaced with a weird black rectangle.
On the Define new Multilevel list I don't see Chapitre 2 but an empty field with a small dot pixel on the top left (in the Enter formatting for number: section).
I cannot delete it or remove it. How can I fix this?
I've uploaded a minimal .docx file in base64: https://pastebin.com/rF9jgWCs
Note that https://superuser.com/a/516480/374513 doesn't solve the problem.
