If they are unable to evaluate your actual work, the only way they can evaluate you is based on your verbal contributions during a meeting.
As they are clearly unable to coach you, they are probably relying on you to coach the younger workers.
Just realize that each manager is looking for a different set of things. Some managers would be perfectly happy with you quietly writing applications well.
Nobody knows how to be a manager, and while some with encouragement can learn, some people either don't have the inclination or correct temperament.
I personally would never push someone into management or push the person out if that person was happiest as a individual contributor.
The world needs more makers, not more managers.
All the best!
