ILSpy decompiles namespaces incorrectly

I'm having an issue where ILSpy is decompiling scripts like this:

namespace Sunless.Game.AI;

public class HuntingPlus : AIBehaviour{ code here }

namespace Sunless.Game.AI;

public class HuntingPlus : AIBehaviour{ code here }

Instead of

namespace Sunless.Game.AI
{
public class HuntingPlus : AIBehaviour{ code here }
}

namespace Sunless.Game.AI
{
public class HuntingPlus : AIBehaviour{ code here }
}

Which is a big issue for the around 1000+ scripts it generates. I cannot fix it all manually. Did I configure something wrong?
