Why is my TWS not working?

I have tried multiple YT tutorial and done everything they did but it still doesnt work.
When i press change radar/irst mode to tws i wont soft lock anything i have tried almost every altitude from 100 - 5000. Does anybody know what i do wrong or what im missing?
Thank you.

Was your TWS set to a proper range to detect the said aircraft?

You aren’t locking aircraft @ 30km away when your radar is set to 19km…

Just a thought.
