Hi @Regina Henschel ,
In MS-OI29500 2.1.558 Part 1 Section 17.18.93, ST_TextDirection (Text Flow Direction) there is a behavior note regarding this:
d. The standard states that lrV orients the text from bottom to top, then left to right, rotated.
Word does not respect this value when used at the section level.
Does this explain what you see?
