Using TL18 on Win64 it produces a large chapter number on the right side above the chapter name -- I do not know what it should look like, so I won't say it works. It clearly fails with the 2018-07-13 beta, producing an odd graphic where the MP-generated digit should be: and fails in the same manner with the 2018-07-17 beta. -- Rik
