Tenant dashboard error

I have noticed that in v4 version, when I select a tenant, in dashboard section, device activation graph I have more devices that real tenant number of devices I have created. Into the tenant I have 96 devices and I see 646 into the dashboard graph. Could you tell me where is located the information that chirpstack uses to calculate the dashboard resume or what could be the problem that I have? The devices has been create throw the api passing the applicationID and deviceprofileID.
