Command Line build does not update linked documents

Using a simple command line build which works almost fine. Only issue is that for any linked documents we have it does not auto-generate the topics. Similarly, in the GUI itself there seems to be no way to tell it to update all topics from linked documents. e.g. we have about 20 linked word docs, and I have to select each one and command it to update the topics.

Examining the command line help ("C:\Program Files\Adobe\Adobe RoboHelp 2020\RoboHelp.exe" --cl  -help) yeilded no extra params for this either.

Finally, the available command line parameters are very unclear. e.g. I am using -o and -p, which results in a working site (albeit without linked document updates) but there is also a -u param which states 'Publish the selected profiles in the output preset' - but the publish is happening anyway without this parameter.

Finally the help emmitted for u goes on to say '(Note: if both publishing and output generation related arguments are provided, publishing is prioritized)', which makes no sense - ie why would you want to publish BEFORE generating output?
