Random "0" in my frontend card and I can't figure out why

[angrycatmeowmeow]

I updated my legacy sensor.yaml config to the newer template.yaml config and transferred everything over. Everything seems to be working fine but now I've got this weird zero on my custom card and I can't figure out why it's doing that.

type: custom:mail-and-packages-card

camera_entity: camera.mail_usps_camera
deliveries_message: sensor.mail_usps_delivering
