I'm not sure if this is a bug; moreover I think it would be a feature request, so I use this category.
From a "virtual GPS" content I build my gpx. When configuring the build process (before putting the task into the jobs queue), I can select to "refresh the corrected coordinates" (near there it says, when this has been done the last time).
Using "the corrected coordinates" is selected (by default), too. When the job has done, I get the GPX archive with corrected coordinates for true.
Now going back into the virtual GPS and the map view, I'd exspect/request to find these corrected coordinates therein, too.
Thanks and Regards
