After changing the Bearing configurations did you rebuild?
You can force rebuild using ctrl Q
If the bearing is not cutting in a section, its IsFastener property is set to = 1. Edit the bearing file and delete the IsFastener property, or try setting IsFastener=0.
Check if the new bearings are solids? If they are imported geometry and it's only surface it may be the cause of your problem. Maybe not because I think you will not be able to create the section at all, but it's still worth a look.
