This is an impression-of-quality issue.
The syntax highlighting in the script editor is incomplete.
This needs a more thorough inspection, but here's some things I see from looking at the Hohmann sample:
- DifferentialCorrector is blue, but Spacecraft, Propagator, ForceModel, etc. aren't
- MaxStep is blue, but no other fields of Propagator are
- true/false are blue, but yes/no and on/off aren't
- Comments aren't highlighted
- keywords in comments are highlighted
- Vary command Lower option is highlighted, but Perturbation isn't
- transpose operator is highlighted like a mismatched string quote
