Export formatting to Word doc is messy

Hi Justin.

I’ve just recently been told by my artist that the exporting from superscript into a word document has never been accurate and clean.

I type my scripts up on an iMac then export to word for him to complete.
I assumed it was looking good and always sent them straight through.
4 issues in he tell’s me that its always been a mess

heres what I see

Heres what he sees

Heres my save setup

Can you identify the issue?
the formatting is pretty random at points.
