Or like what others mentioned, internal KP appointments.

Doing a lot of work within your paygrade, merely makes you a hardworking worker. Which might explain your good performance bonus.

A GEO3 can be a member of multiple committees, coordinator for many levels and streams, be teacher in charge of CCA. But these are considered routine work, and usually the officer is just executing other people's ideas, helping to achieve other people's KPI.

Ask your RO if you can be reassigned to other roles that allow you showcase your ability to perform above your paygrade.
