Seems you mostly have the same settings as me but of course my 'Measurement system' is 'Metric' and 'Use native digits' I have set to 'Never'.
But I changed my settings and it made no difference - feet & inch dims were fine.
But I see you are indeed using Archicad 7.0 with Plotmaker.
Version 7 was never designed to run on Windows 8 Operating System so that could well be your problem.
I wouldn't be surprised if you have a number of other issues as well.
In fact I am surprised you have it running at all.
