Hello,

Just out of interest, which strength/weakness were you trying to set?

It is not possible to have the same strength and weakness at the same circuit, and, despite being visually possible, you cannot set Cooling or Reliability as the Engine Weakness. 
These being a selectable option is a bug and has been referred to the developers for investigation.
