How does allocation groups works?

im running cast ai in aws eks cluster 1.23
i'm trying to create allocations groups based on teams. I have already selected by the namespace and a few tags like app.kubernetes.io/name=service-name or app.kubernetes.io/instance=service-name but it doesnt work so far. if i go to the workloads i can see the current cost of all services running and also in the namespace section i can see the current cost of the namespace.

it's like there is no recognition about the tags i'm selecting. also i have already created a new tag for the deployment like "team": "some-team" and it's not working so far.

can you lend me a hand with this?
