Either the postprocessor isn’t correct; there’s an issue with arc moves; Or there’s a bug in Aspire. I’ve debugged part of the problem, but I’m not using Aspire (and don’t intend to) so it’s up to someone else to try and fix it.
You can manually edit the files using a tool like ncviewer to see were it goes wrong (see linked post) or in a lot of cases just remove them without too much of a problems in the end results.
According to the github page:
the issue was solved. If it still doesn’t work for you either there is still a bug. In that case report it.
Or you’re using an outdated version of the post-processor.
