I have a MAC. To be clear, this is a problem I encounter when typing into the Compose Box here... Not really in Word but I suppose you're indicating that the Word setting could be causing problems here? Composing and copying in Word and pasting here has been my workaround tip.
My MAC Word Options:
Word>Preferences>Edit> Screenshot of options attached.
I do not see Use the Insert key to control overtype mode
I do see Use overtype mode and it was already not checked.
