Optional arguments doesn't work on v2

[Syrent]

After adopting Cloud V2, I've encountered an issue with optional values not functioning as intended, or it's possible I may have misconfigured something in my code.

Snippet from my code:

optional("leader", StringParser.stringParser()) {
    defaultValue(DefaultValue.dynamic { context ->
        context.stickySender().name
    })
}

stickySender is one of my kotlin extensions

Result:
