I don't know why, but your splines appear to be broken. Neither can be edited or converted to DWire in Draft WB. They appear to have no points!

I traced new BSplines along the existing ones and the sweeps were fine.

Could you please post your version info from Help->About FreeCAD?
Were the splines made in an older version?

BSpline001 says it has 8 points, but the last 4 are zeroes.

BSpline has 7 points and the last 3 are zeroes.

If you recreate the splines I think you'll be alright. Don't know how the splines came to be this way. Would need more details on how they were created.

This is a problem in the model, not the software, so this ticket will be closed.
