Since May 31, 2018, FE Wheel uses a separate orbs set.
To edit that, go to Prefs->Fin.Ephem and press Edit FE wheel orbs button





You will be directed to Orbs Editor.
There you my edit the orbs individually or assign to all of them some value.
For example, to set for all aspects 1° orb, type in "1" in default orb value edit and click Fill all orbs with above value button.




Press OK to save edited orbs set and exit Orbs Editor.
Now in FE Wheel you will see only the aspects that are closer than 1 degree.
