Generate Code for Shell and C# feature is buggy

My mongo shell script:

db.test.aggregate(

{ $match: { $and: [ {isActive: {$eq: true} }, { id: {$eq: '4011caa5-6d09-4a3a-83e1-ca70c9b65457'}}] }},

{ $unwind: { path: '$departmentDegrees'} },

{ $match : {'departmentDegrees.isActive': { $eq : true} }},

{

$project: {

NoSQLBooster Generated Code for C#: This returns completely different result sets.
