Spurious on the FSWP screen are not in the exported trace list

As you already said, those peaks are sprurious. The sprurious are not part of the phase noise trace, they are just an information for the user that at that point are spurious. If you set a marker on the spurious you also can see that the unit of the spurious is dBc and not dbc/Hz:

If you want to see / export those peaks, please create a spurious list:
