Podman can not kill containers: not running, but state improper

When I run podman container kill -a, I get can only kill running containers. 11d887d57069b3ee630fd6f1b13d600485c34f5020ff09fec65f4e31dd7242a5 is in state configured: container state improper can only kill running containers. 2132c0543eedbe3c4ee8680da508fea6251d38107d5e707f260eb5aa8549409d is in state configured: container state improper can only kill running containers. 2db317cc73ec92e434fda88653f872e4c4cf07e9f32c0c29ecc5e69515beb96d is in state exited: container state improper can only kill running containers. 465d133dec7a568bd8a6231036e1c489b6a6f88c65154629d75ce4161fb6e3c4 is in state exited: container state improper Subsequent runs still show the containers. How can I get rid of them?
