netbox.redis.secretName rendered incorrectly

[sergey-kalikin-adjust]

When trying to use external Redis containers do not start with an error:
MountVolume.SetUp failed for volume "secrets" : secret "netbox-redis" not found
I have externalRedis.existingSecretName empty. Secret name should be netbox-external-redis:

kubectl get secrets -n netbox                                                                                               
NAME                           TYPE                 DATA   AGE
netbox-external-redis          Opaque               2      3m42s
netbox                         Opaque               7      3m42s
netbox-external-db             Opaque               1      3m42s
sh.helm.release.v1.netbox.v1   helm.sh/release.v1   1      3m42s

Looks like this name:

Should be rendered similar to db:
