Fixed DEFAULTMODEL & MODEL Enum regressions

[nikita488]

1. Methods containing the DEFAULTMODEL enumeration argument did not include any of the models on completion because the enumeration name was compared to the old enumeration name “CARPEDMODEL” instead of the current name “DEFAULTMODEL”.
2. Level models were never parsed for completion because the method that queries models and parses them always used the “default” mode, i.e., output only DEFAULT models.
